OCTAL BUS TRANSCEIVER

WITH 3-STATE INVERTING

OUTPUTS

DESCRIPTION

The U74LVC640 is designed for asynchronous communication

between data buses and has inverting outputs. While the

direction-control(DIR) input is high, data transmits from the A bus to

the B bus. In contrast, Data transmits from the B bus to the A bus

DIR input is low. The output-enable(OE) will disable the device and

isolate from the buses when high voltage is applied on it.

FEATURES

* Supply Voltage Range From 1.2V to 3.6V

* Input Accept Voltages up to 5.5V

* Partial-Power-Down Mode Operation

* Max t

PD

is 6.3ns at 3.3V
