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.
