HD74BC244A
Octal Buffers/Line Drivers With 3 State Outputs
REJ03D0281–0300Z (Previous ADE-205-007A (Z))
Rev.3.00 Jul.16.2004
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 (1G and 2G). 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
