Overview
The onsemi 74LCX240SJ is an inverting octal buffer and line driver designed for low voltage VCC applications with capability of interfacing to a 5 V signal environment. It features 5 V tolerant inputs and outputs, operates within a 1.65 V to 5.5 V supply range, and provides ±24 mA output drive at VCC = 3.0 V. The device implements proprietary noise/EMI reduction circuitry and supports live insertion/withdrawal. It offers power-down high impedance inputs and outputs, with propagation delay (tPD) max of 6.5 ns at VCC 3.3 V.
