74HC244-Q100; 74HCT244-Q100
Octal buffer/line driver; 3-state
Rev. 1 — 7 August 2012
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 VCC.
This product has been qualified to the Automotive Electronics Council (AEC) standard
Q100 (Grade 1) and is suitable for use in automotive applications.
