IDT74LVCH16652 3.3V CMOS 16-BIT BUS TRANSCEIVER AND REGISTER INDUSTRIAL TEMPERATURE RANGE 3.3V CMOS 16-BIT BUS TRANSCEIVER AND REGISTER WITH 3-STATE OUTPUTS, 5V TOLERANT I/O, BUS-HOLD FEATURES: IDT74LVCH16652 DESCRIPTION: • Typical tSK(o) (Output Skew) < 250ps • ESD > 2000V per MIL-STD-883, Method 3015; > 200V using machine model (C = 200pF, R = 0) • VCC = 3.3V ± 0.3V, Normal Range • VCC = 2.7V to 3.6V, Extended Range µ W typ. static) • CMOS power levels (0.4µ • All inputs, outputs, and I/O are 5V tolerant • Supports hot insertion • Available in SSOP and TSSOP packages This 16-bit transceiver and register is built using advanced dual metal CMOS technology. This high-speed, low power device is organized as twoindependent 8-bit bus transceivers with 3-state D-type registers. The control circuitry is organized for multiplexed transmission of data between A bus and B bus either directly or from the internal storage registers. Each 8-bit transceiver/register features complementary Output Enable (OEAB and OEBA) inputs to control the transciever functions and Select lines (SAB and SBA) to select either real-time data or stored data. Separate clock inputsare provided for A and B port registers. Data on the A or B data bus, or both,can be stored in the internal registers by the low-to-high transitions at theappropriate clock pins. Flowthrough organization of signal pins simplifieslayout. All inputs are designed with hysteresis for improved noise margin. The LVCH16652A has been designed with a ±24mA output driver. This driver is capable of driving a moderate to heavy load while maintaining speed performance. The LVCH16652A has “bus-hold” which retains the inputs’ last state whenever the input bus goes to a high impedance. This prevents floating inputs and eliminates the need for pull-up/down resistors. DRIVE FEATURES: • High Output Drivers: ±24mA • Reduced system switching noise APPLICATIONS: • 5V and 3.3V mixed voltage systems • Data communication and telecommunication systems FUNCTIONAL BLOCK DIAGRAM 1OEBA 56 2OEBA 29 1OEAB 1 2OEAB 28 1CLKBA 55 2CLKBA 30 1SBA 54 2SBA 31 1CLKAB 2 2CLKAB 27 2SAB 26 1SAB 3 B REG B REG D D C 1A1 5 C 52 A REG 1B1 D 2A1 15 42 A REG 2B1 D C C TO 7 OTHER CHANNELS TO 7 OTHER CHANNELS The IDT logo is a registered trademark of Integrated Device Technology, Inc.

Data input functions are always enabled, i.e. data at the bus pins will be stored on every LOW-to-HIGH transition on the clock inputs. 3. Select control = L: clocks can occur simultaneously. Select control = H: clocks must be staggered to load both registers.
