OCTAL BUS TRANSCEIVERS WITH

3-STATE OUTPUTS

DESCRIPTION

The U74HCT640 is a octal bus transceivers with 3-state

outputs. It is designed for asynchronous two-way communication

between data buses. Depending on the direction-control (DIR) input,

data are transmitted from the A bus to the B bus or from B bus to the

A bus.

When OE is high, the buses are effectively isolated. When

OE

is low, the buses are enable.

FEATURES

* Inputs are TTL-voltage compatible

* Typical tPD of 12ns at 5.5V, CL=50pF

* Low power consumption, ICC = 8μA (Max) at 5.5V

* ±6mA output driver at 4.5V
