HD74BC244A
Octal Buffers/Line Drivers With 3 State Outputs
ADE-205-007A (Z)
2nd. Edition
March 1993
Description
The HD74BC244A 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 inverter drivers with
three state outputs in a 20 pin package. This device is a non inverting buffer and has two active low
enables (1
G
and 2
G
). Each enable independently controls 4 buffers.
Features
Input/Output are at high impedance state when power supply is off.
Built in input pull up circuit can make input pins be open, when not used.
TTL level input
Wide operating temperature range
Ta = –40 to + 85°C
