74HC244D 74HC244; 74HCT244
Octal buffer/line driver; 3-state
Rev. 03 ― 22 December 2005 Product data sheet
1. General description
The 74HC244; 74HCT244 is a high-speed Si-gate CMOS device and is pin compatible
with Low-power Schottky TTL (LSTTL).
The 74HC244; 74HCT244 has octal non-inverting buffer/line drivers with 3-state outputs.
The 3-state outputs are controlled by the output enable inputs 1OE and 2OE. A HIGH on
nOE causes the outputs to assume a high-impedance OFF-state. The 74HC244;
74HCT244 is identical to the 74HC240; 74HCT240 but has non-inverting outputs.
