The device is byte controlled. Each � 26Ω series resistors in A port outputs byte has separate 3-STATE control inputs which can be � t (B to A) shorted together for full 16-bit operation. The T/R inputs PD determine the direction of data flow through the device. 3.4 ns max for 3.0V to 3.6V V CC The OE inputs disable both the A and B ports by placing 4.3 ns max for 2.3V to 2.7V V CC them in a high impedance state. 8.6 ns max for 1.65V to 1.95V V The 74VCX162245 is designed for low voltage (1.65V to CC 3.6V) V applications with I/O compatibility up to 3.6V. CC � Power-down high impedance inputs and outputs The 74VCX162245 is also designed with 26Ω series resis- � Supports live insertion/withdrawal (Note 1) tance in the A Port outputs. This design reduces line noise � Static Drive (I /I A outputs) OH OL in applications such as memory address drivers, clock driv- ±12 mA @ 3.0V V ers, and bus transceivers/transmitters. CC The 74VCX162245 is fabricated with an advanced CMOS ±8 mA @ 2.3V V CC technology to achieve high speed operation while maintain- ±3 mA @ 1.65V V CC ing low CMOS power dissipation. � Uses patented noise/EMI reduction circuitry � Latchup performance exceeds 300 mA � 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 V through a pull-up resistor; the minimum CC value of the resistor is determined by the current-sourcing capability of the driver.
