74ABT540N,602

Buffers, Drivers, Receivers, Transceivers Overview

The NXP USA Inc. 74ABT540N,602 is an octal inverting buffer with 3-State outputs manufactured using high-performance BiCMOS technology. It operates within a DC supply voltage range of 4.5 V to 5.5 V and supports an operating free-air temperature range from -40 °C to +85 °C. The device provides an output capability of +64 mA for low-level states and -32 mA for high-level states. Propagation delay (tPLH/tPHL) is typically 3.1 ns at VCC = 5 V with a 50 pF load. Quiescent supply current (ICCZ) is limited to a maximum of 250 μA at VCC = 5.5 V.
