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

3.6V) VCC applications with I/O compatibility up to 3.6V.

The 74VCX16245 is fabricated with an advanced CMOS

technology to achieve high speed operation while maintain-

ing low CMOS power dissipation.

Features

s 1.2V to 3.6V VCC supply operation

s 3.6V tolerant inputs and outputs

s tPD

2.5 ns max for 3.0V to 3.6V VCC

s Power-off high impedance inputs and outputs

s Supports live insertion/withdrawal (Note 1)

s Static Drive (IOH/IOL)

r24 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

s Also packaged in plastic Fine-Pitch Ball Grid Array

(FBGA)

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.
