74ABT16245

16-Bit Transceiver with 3-STATE Outputs

General Description

The ABT16245 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 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.

Features

s Bidirectional non-inverting buffers

s Separate control logic for each byte

s 16-bit version of the ABT245

s A and B output sink capability of 64 mA, source

capability of 32 mA

s Guaranteed output skew

s Guaranteed multiple output switching specifications

s Output switching specified for both 50 pF and

250 pF loads
