DESCRIPTION

The 74VCXH162245 is a low voltage CMOS 16

BIT BUS TRANSCEIVER (3-STATE) fabricated

with sub-micron silicon gate and five-layer metal

wiring C

and very high speed 2.3 to 3.6V applications; it

can be interfaced to 3.6V signal environment for

both inputs and outputs.

This IC is intended for two-way asynchronous

communication between data buses; the direction

of data transmission is determined by DIR input.

The two enable inputs nG can be used to disable

the device so that the buses are effectively

isolated. The device circuits is including 26

ries resistance in the A port outputs. These resis-

tors permit to reduce line noise in high speed ap-

plications. Bus hold on data inputs is provided in

order to eliminate the need for external pull-up or

pull-down resistor.
