HD74BC623A

Octal Bus Transceivers With 3 State Outputs

REJ03D0289–0200Z

(Previous ADE-205-025 (Z))

Rev.2.00

Jul.16.2004

Description

The HD74BC623A provides high drivability and operation equal to or better than high speed bipolar standard logic IC

by using Bi-CMOS process. The device features low power dissipation that is about 1/5 of high speed bipolar logic IC.

When the frequency is 10 MHz. The device has eight bus transceivers with three state outputs in a 20 pin package.

This device allows data transmission from the A bus to the B bus or from the B bus to the A bus depending upon the

logic levels at the enable inputs (GBA and GAB). The enable inputs can be used to disable the device so that the buses

are effectively isolated.

Features

•

Input/Output are at high impedance state when power supply is off.

Input pins can be open, when not used, owing to built in input pull up circuit.

Input is TTL level.

Wide operating temperature range

Ta = –40 to +85°C.
