1 / 22 page 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. 2. Features s Octal bus interface s Non-inverting 3-state outputs s Complies with JEDEC standard no. 7A s ESD protection: x HBM EIA/JESD22-A114-C exceeds 2000 V x MM EIA/JESD22-A115-A exceeds 200 V s Multiple package options s Specified from −40 °Cto+85 °C and from −40 °C to +125 °C 3.
