74AHCT240

74AHCT240 Octal buffer/line driver; inverting; 3-state Rev. 6 — 29 June 2020 Product data sheet 1. General description The 74AHCT240 is an 8-bit inverting buffer/line driver with 3-state outputs. This device can be used as two 4-bit buffers or one 8-bit buffer. It features two output enables (1OE and 2OE), each controlling four of the 3-state outputs. A HIGH on nOE causes the outputs to assume a high-impedance OFF-state. Inputs are over voltage tolerant. This feature allows the use of these devices as translators in mixed voltage environments. 2. Features and benefits Balanced propagation delays All inputs have a Schmitt-trigger action Inputs accepts voltages higher than VCC Operates with TTL input levels ESD protection: HBM JESD22-A114F exceeds 2000 V CDM JESD22-C101D exceeds 1000 V Multiple package options Specified from -40 °C to +85 °C and from -40 °C to +125 °C 3.
