74HC244PW 数字逻辑芯片

74HC244 GENERAL DESCRIPTION

The 74HC244/HCT244 are high-speed Si-gate CMOS devices and are pin compatible with low power Schottky TTL (LSTTL). They are specified in compliance with JEDEC standard no. 7A. The 74HC244/HCT244 are 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 “244” is identical to the “240” but has non-inverting outputs.
