74HC240; 74HCT240 Octal buffer/line driver; 3-state; inverting Rev. 03 — 2 August 2007 Product data sheet 1. General description The 74HC240; 74HCT240 is a high-speed Si-gate CMOS device and is pin compatible with Low-Power Schottky TTL (LSTTL). The 74HC240; 74HCT240 is a dual octal inverting buffer/line driver 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 74HC240; 74HCT240 is similar to the 74HC244; 74HCT244 but has inverting outputs. 2. Features s s s s Inverting 3-state outputs Multiple package options Complies with JEDEC standard no. 7 A ESD protection: x HBM JESD22-A114-D exceeds 2000 V x MM JESD22-A115-A exceeds 200 V s Specied from 40 °C to +85 °C and from 40 °C to +125 °C 3.
