Advanced CMOS TTL Input – 74ACT244

 

 

 

 

Octal 3-State Non-Inverting Buffer / Line Driver / Line Receiver in bare die form

Rev 1.0

24/04/19

Outputs Source/Sink 24mA

Low input current: 1µA

Inputs directly accept TTL

 

 

 

 

The 74ACT244 is produced on a 1.5µm 5V CMOS process

combining high speed LSTTL performance with CMOS low

power. The device can be used as two 4-bit buffers or one

8-bit buffer & features non-inverting inputs with two output

enables, each controlling four of the 3-state outputs. The

device is designed to improve performance & density in

clock drivers, 3-state memory address drivers & bus

orientated transmitters and receivers. Inputs include clamp

diodes that enable the use of current limiting resistors to

directly accept TTL without use of pull-up resistors.

Description

Outputs directly interface CMOS, NMOS and TTL

Operating voltage range: 4.5V to 5.5V

Function compatible with 74LS244

Lower power alternative to bipolar logic.
