描述 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.

特性 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.
