74HC240 74HCT240 Octal buffer/line driver 3-state inverting Rev. 4 25 February 2016 Product data sheet 1. General description The 74HC240 74HCT240 is an 8-bit inverting buffer/line driver with 3-state outputs. The device can be used as two 4-bit buffers or one 8-bit buffer. The device 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 include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of V . CC 2. Features and benefits Complies with JEDEC standard JESD7A Input levels: For 74HC240: CMOS level For 74HCT240: TTL level Inverting 3-state outputs ESD protection: HBM JESD22-A114F exceeds 2000 V MM JESD22-A115-A exceeds 200 V Multiple package options Specified from 40 Cto+85 C and from 40 Cto+125 C 3.
