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