The low on-state resistance of the switch allows connections to be made with minimal propagation delay. The device can be used as a 22-bit switch, with the gates cascaded together to a reference transistor. The low-voltage side of each pass transistor is limited to a voltage set by the reference transistor. This is done to protect components with inputs that are sensitive to high-state voltage-level overshoots.

Because, within the device, the characteristics from transistor to transistor are equal, the maximum output high-state voltage (VOH) is approximately the reference voltage (VREF), with minimal deviation from one output to another. This is a benefit of the TVC solution over discrete devices. Because the fabrication of the transistors is symmetrical, either port connection of each bit can be used as the low-voltage side, and the I/O signals are bidirectional through each FET.

These standards define, among other things, the I/O voltage levels at which the bus communicates. Examples include the GTL+ host bus, the AGP graphics port, and the PCI local bus. In new designs, the system components must communicate with existing bus infrastructure. Providing an evolutionary upgrade path is important in the design of PC architecture, but the existing bus standards must be preserved. To achieve the ever-present need for smaller, faster, lighter devices that draw less power, yet have faster performance, most new high-performance digital integrated circuits are designed and produced with advanced submicron semiconductor process technologies. These devices have thin gate-oxide or short channel lengths and very low absolute-maximum voltages that can be tolerated at the inputs/outputs (I/Os) without causing damage. In many cases, the I/Os of these devices are not tolerant of the high-state voltage levels on the preexisting buses with which they must communicate. Therefore, it became necessary to protect the I/Os of devices by limiting the I/O voltages. The Texas Instruments (TI) translation voltage-clamp (TVC) family is designed specifically for protecting sensitive I/Os (see Figure 2). The information in this data sheet describes the I/O-protection application of the TVC family and should enable the design engineer to successfully implement an I/O-protection circuit utilizing the TI TVC solution.

Thin Gate-Oxide Protection Application POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 5 SCDS087G − APRIL 1999 − REVISED APRIL 2005 APPLICATION INFORMATION TVC voltage-limiting application For the voltage-limiting configuration, the common GATE input must be connected to one side (A or B) of any one of the transistors (see Figure 3). This connection determines the VBIAS input of the reference transistor. The VBIAS input is connected through a pullup resistor (typically 200 kΩ ) to the VDD supply. A filter capacitor on VBIAS is recommended. The opposite side of the reference transistor is used as the reference voltage (VREF) connection. The VREF input must be less than VDDREF − 1 V to bias the reference transistor into conduction. The reference transistor regulates the gate voltage (VGATE) of all the pass transistors. VGATE is determined by the characteristic gate-to-source voltage difference (VGS) because VGATE = VREF + VGS. The low-voltage side of the pass transistors has a high-level voltage limited to a maximum of VGATE − VGS, or VREF.

Figure 4 shows the test configuration for the TI SPICE simulations. The results, shown in Figures 5 and 6, show the current through a pass transistor versus the voltage at the source for different reference voltages. The plots of the dc characteristics clearly reveal that the device clamps at the desired reference voltage for the varying device environments. Figure 5 shows the V-I characteristics with low reference voltages and a reference-transistor drain-supply voltage of 3.3 V. To further investigate the spread of the V-I characteristic curves, VREF was held at 2.5 V and IREF was increased by raising VDDREF (see Figure 6). The result was a tighter grouping of the V-I curves. VDDREF GATE VDDPASS RDREF RDPASS VBIAS VDPASS VREF VSPASS Figure 4.

The flexibility of TVC enables a low-voltage migration path for advanced designs to align with industry standards. frequently asked questions (FAQs) 1. Q: Can any of the transistors in the array be used as the reference transistor? A: Yes, any transistor can be used as long as its VBIAS pin is connected to the GATE pin. 2. Q: In the recommended operating conditions table of the data sheet, the typical VBIAS is 3.3 V. Should VBIAS be equal to or greater than VREF on the reference transistor? A: VBIAS is a variable that is determined by VREF. VBIAS is connected to VDD through a resistor to allow the bias voltage to be controlled by VREF. VDD can be as high as 5.5 V. VREF needs to be at least 1 V less than VDDREF on the reference transistor. 3. Q: Do both A and B ports have 5-V I/O tolerance or is 5-V I/O tolerance provided only on the low-voltage side? A: Both ports are 5-V tolerant. 10 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 PACKAGE OPTION ADDENDUM www.ti.com 27-Sep-2007 PACKAGING INFORMATION Orderable Device Status (1) Package Type Package Drawing Pins Package Eco Plan (2) Qty 74TVC16222ADGGRE4 ACTIVE TSSOP DGG 48 2000 Green (RoHS & no Sb/Br) CU NIPDAU Level-1-260C-UNLIM 74TVC16222ADGGRG4 ACTIVE TSSOP DGG 48 2000 Green (RoHS & no Sb/Br) CU NIPDAU Level-1-260C-UNLIM 74TVC16222ADGVRE4 ACTIVE TVSOP DGV 48 2000 Green (RoHS & no Sb/Br) CU NIPDAU Level-1-260C-UNLIM 74TVC16222ADGVRG4 ACTIVE TVSOP DGV 48 2000 Green (RoHS & no Sb/Br) CU NIPDAU Level-1-260C-UNLIM SN74TVC16222ADGGR ACTIVE TSSOP DGG 48 2000 Green (RoHS & no Sb/Br) CU NIPDAU Level-1-260C-UNLIM SN74TVC16222ADGVR ACTIVE TVSOP DGV 48 2000 Green (RoHS & no Sb/Br) CU NIPDAU Level-1-260C-UNLIM SN74TVC16222ADL ACTIVE SSOP DL 48 25 Green (RoHS & no Sb/Br) CU NIPDAU Level-1-260C-UNLIM SN74TVC16222ADLG4 ACTIVE SSOP DL 48 25 Green (RoHS & no Sb/Br) CU NIPDAU Level-1-260C-UNLIM SN74TVC16222ADLR ACTIVE SSOP DL 48 1000 Green (RoHS & no Sb/Br) CU NIPDAU Level-1-260C-UNLIM SN74TVC16222ADLRG4 ACTIVE SSOP DL 48 1000 Green (RoHS & no Sb/Br) CU NIPDAU Level-1-260C-UNLIM Lead/Ball Finish MSL Peak Temp (3) (1) The marketing status values are defined as follows: ACTIVE: Product device recommended for new designs.

Except where mandated by government requirements, testing of all parameters of each product is not necessarily performed. TI assumes no liability for applications assistance or customer product design. Customers are responsible for their products and applications using TI components. To minimize the risks associated with customer products and applications, customers should provide adequate design and operating safeguards. TI does not warrant or represent that any license, either express or implied, is granted under any TI patent right, copyright, mask work right, or other TI intellectual property right relating to any combination, machine, or process in which TI products or services are used. Information published by TI regarding third-party products or services does not constitute a license from TI to use such products or services or a warranty or endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the third party, or a license from TI under the patents or other intellectual property of TI. Reproduction of TI information in TI data books or data sheets is permissible only if reproduction is without alteration and is accompanied by all associated warranties, conditions, limitations, and notices. Reproduction of this information with alteration is an unfair and deceptive business practice. TI is not responsible or liable for such altered documentation. Information of third parties may be subject to additional restrictions. Resale of TI products or services with statements different from or beyond the parameters stated by TI for that product or service voids all express and any implied warranties for the associated TI product or service and is an unfair and deceptive business practice. TI is not responsible or liable for any such statements. TI products are not authorized for use in safety-critical applications (such as life support) where a failure of the TI product would reasonably be expected to cause severe personal injury or death, unless officers of the parties have executed an agreement specifically governing such use. Buyers represent that they have all necessary expertise in the safety and regulatory ramifications of their applications, and acknowledge and agree that they are solely responsible for all legal, regulatory and safety-related requirements concerning their products and any use of TI products in such safety-critical applications, notwithstanding any applications-related information or support that may be provided by TI. Further, Buyers must fully indemnify TI and its representatives against any damages arising out of the use of TI products in such safety-critical applications. TI products are neither designed nor intended for use in military/aerospace applications or environments unless the TI products are specifically designated by TI as military-grade or "enhanced plastic." Only products designated by TI as military-grade meet military specifications. Buyers acknowledge and agree that any such use of TI products which TI has not designated as military-grade is solely at the Buyer's risk, and that they are solely responsible for compliance with all legal and regulatory requirements in connection with such use. TI products are neither designed nor intended for use in automotive applications or environments unless the specific TI products are designated by TI as compliant with ISO/TS 16949 requirements. Buyers acknowledge and agree that, if they use any non-designated products in automotive applications, TI will not be responsible for any failure to meet such requirements.
