HD74HCT640/HD74HCT643

Octal Bus Transceivers (with 3-state outputs)

ADE-205-562 (Z)

1st. Edition

Sep. 2000

Description

Both the HD74HCT640 and the HD74HCT643 have one active low enable input (G), and a direction

control (DIR). When the DIR input is high, data flows from the A inputs to the B outputs. When DIR is

low, data flows from B to A.

The HD74HCT640 transfers inverted data from one bus to the other. The HD74HCT643 transfers inverted

data from the A bus to the B bus and non-inverted data from the B bus to the A bus.

Features

•

LSTTL Output Logic Level Compatibility as well as CMOS Output Compatibility

•

High Speed Operation: t

(A to B) = 14.5 ns typ (C

= 50 pF)

High Output Current: Fanout of 15 LSTTL Loads

Wide Operating Voltage: V

= 4.5 to 5.5 V

Low Input Current: 1 µA max

Low Quiescent Supply Current: I

(static) = 4 µA max (Ta = 25°C)
