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

interface inputs to voltages in excess of VCC. Device inputs

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.
