74VCX16245

Low Voltage 16-Bit Bidirectional Transceiver

with 3.6V Tolerant Inputs and Outputs

General Description

The VCX16245 contains sixteen non-inverting bidirectional

buffers with 3-STATE outputs and is intended for bus ori-

ented 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 74VCX16245 is designed for low voltage (1.2V to

The 74VCX16245 is fabricated with an advanced CMOS

technology to achieve high speed operation while maintain-

ing low CMOS power dissipation.

Features

s Also packaged in plastic Fine-Pitch Ball Grid Array

(FBGA)

Note 1: To ensure the high-impedance state during power up or power

value of the resistor is determined by the current-sourcing capability of the

driver.

Ordering Code:

Note 2: Ordering code “G” indicates Trays.

Note 3: Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
