74AHCT244

Octal Buffer/Line Driver

with 3-State Outputs

GENERAL DESCRIPTION

FEATURES

The 74AHCT244 is an octal buffer/line driver with non-

inverting 3-state outputs, and it is designed for 4.5V to

5.5V V_CCoperation.

● Supply Voltage Range: 4.5V to 5.5V

● Input Accept Voltages Higher than the Supply

Voltage

● +8mA/-8mA Output Current

The device can be used as two 4-bit buffers or one 8-bit

● 3-State Buffers

buffer. The 1OE and 2OE are two output enable inputs,

and each controls four of the 3-state outputs. When

● -40℃ to +125℃ Operating Temperature Range

● Available in a Green SOIC-20 Package

nOE is set high, the outputs are in high-impedance

state. When nOE is set low, data transmits from the

nAn inputs to the nYn outputs.

period of power-up or power-down, and the minimum

resistance depends on the current-sinking capability of
