1 / 9 page © 2005 Fairchild Semiconductor Corporation DS500048 www.fairchildsemi.com October 1996 Revised June 2005 74VCX162245 Low Voltage 16-Bit Bidirectional Transceiver with 3.6V Tolerant Inputs and Outputs and 26 : Series Resistors in A Port Outputs General Description The VCX162245 contains sixteen non-inverting bidirec- tional buffers with 3-STATE outputs and is intended for bus oriented applications. The device is byte controlled. Each byte has separate 3-STATE control inputs which can be shorted together for full 16-bit operation. The T/R inputs determine the direction of data flow through the device. The OE inputs disable both the A and B ports by placing them in a high impedance state. The 74VCX162245 is designed for low voltage (1.4V to 3.6V) VCC applications with I/O compatibility up to 3.6V. The 74VCX162245 is also designed with 26 : series resis- tance in the A Port outputs. This design reduces line noise in applications such as memory address drivers, clock driv- ers, and bus transceivers/transmitters. The 74VCX162245 is fabricated with an advanced CMOS technology to achieve high speed operation while maintain- ing low CMOS power dissipation. Features s 1.4V to 3.6V VCC supply operation s 3.6V tolerant inputs and outputs s 26 : series resistors in A port outputs s tPD (B to A) 3.4 ns max for 3.0V to 3.6V VCC s Power-down high impedance inputs and outputs s Supports live insertion/withdrawal (Note 1) s Static Drive (IOH/IOL A outputs) r12 mA @ 3.0V VCC s Uses patented noise/EMI reduction circuitry s Latchup performance exceeds 300 mA s ESD performance: Human body model ! 2000V Machine model !200V Note 1: To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pull-up resistor; the minimum value of the resistor is determined by the current-sourcing capability of the driver.
