74HC244-Q100; 74HCT244-Q100

Octal buffer/line driver; 3-state

Rev. 2 — 27 September 2019

Product data sheet

1. General description

The 74HC244-Q100; 74HCT244-Q100 is an 8-bit buffer/line driver with 3-state outputs. The device

can be used as two 4-bit buffers or one 8-bit buffer. The device features two output enables (1OE

and 2OE), each controlling four of the 3-state outputs. A HIGH on nOE causes the outputs to

assume a high-impedance OFF-state. Inputs include clamp diodes. This enables the use of current

limiting resistors to interface inputs to voltages in excess of V_CC

This product has been qualified to the Automotive Electronics Council (AEC) standard Q100

(Grade 1) and is suitable for use in automotive applications.
