U74AHC640L-R20-T Overview

OCTAL BUS TRANSCEIVERS WITH 3-STATE OUTPUTS

UNISONIC TECHNOLOGIES CO., LTD
U74HC640
OCTAL BUS TRANSCEIVERS
WITH 3-STATE OUTPUTS
DESCRIPTION
The
U74AHC640
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 the B bus to
the A bus.
When
OE
is high, the buses are effectively isolated. When
OE
is low, the buses are enable.
