PI74AUC164245 16-Bit 0.8V to 2.7V Scaled Configurable Level Shifting Transceiver with 3-State Outputs Features Description • PI74AUC164245 is designed for low voltage operation: 0.8V to 2.7V Pericom Semiconductor’s AUC series of logic circuits are produced using the Company’s advanced CMOS technology, achieving industry leading performance. • IOFF supports partial Power-Down mode operation • Drive Capability 16mA @ 2.5V The PI74AUC164245 is a 16-bit (dual-octal) noninverting bus transceiver that contains two separate supply rails. B port (VCCB) set to operate at 0.8 to 2.5V and A port (VCCA) set to operate at 0.8 to 2.5V. This arrangement permits universal bidirectional translation over the voltage ranges. • Each supply rail is configurable over supply range • ESD Protection exceeds JESD22 – 2000V Human Body Model (A114-B) – 200V Machine Model (A115-A) The PI74AUC164245 is designed for asynchronous communication between data buses. Data is transmitted from the A bus to the B bus or vice versa, depending on the logic level at the direction control (DIR)input. The output-enable (OE) input is used to disable outputs so buses are isolated. • Latch-up performance exceeds 100mA per JESD 78 • Industrial operation at –40°C to +85°C • Packaging: – 48-pin plastic 240-mil TSSOP (A) – 48-pin plastic 173-mil TVSOP (K) The control pins, 1DIR, 2DIR, 1OE and 2OE are supplied by VCCA. The device is fully specified for partial-power-down applications using IOFF. The IOFF circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down. Block Diagram 1DIR 48 1A1 To ensure the high impedance state during power up or power down, the output-enable (OE) input should be tied to VCC through a pullup resistor, the minimum value of the resistor is determined by the current-sinking capability of the driver. 1 1OE 47 2 1 B1 To Seven Other Channels 2DIR 24 25 2A1 2OE 36 13 2 B1 To Seven Other Channels 1 PS8730 08/17/04 PI74AUC164245 16-Bit 1.2V to 2.7V Level Shifting Transceiver with 3-State Outputs Maximum Ratings (Absolute maximum ratings over operating free-air temperature range (unless otherwise noted) Supply voltage range: VCCA and VCCB.......... –0.5V to 3.6V Input Voltage Range, VI(1): I/O port A ................ –0.5V to 3.6V I/O port B ................ –0.5V to 3.6V Control Inputs ........... –0.5V to 3.6V Voltage Range applied to any output in the high-impedance or Power-Off state, VO (1) : (A Port) .......................... –0.5V to 3.6V (B Port) ..................... –0.5V to 3.6V Voltage Range applied to any output in the highor Low state VO (2) : (A Port) ........... –0.5V to VCCA +0.5V (B Port) ......... –0.5V to VCCB +0.5V Input clamp current, IIK (VI <0)................................... –50mA Output clamp current, IOK (VO <0).............................. –50mA Continuous output current, IO ....................................... ±20mA Continuous current through VCCA, VCCB or GND ..... ±100mA Package thermal impedance, 0JA(3): A package........................... 104°C/W K package .......................... 107°C/W Storage temperature range, TSTG .................... –65°C to 150°C Note: 1.

The package thermal impedance is calculated in accordance with JESD 51. 4. Stresses greater than those listed under MAXIMUM RATINGS may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability.
