74ABT16543BB,518

Buffers, Drivers, Receivers, Transceivers Overview

The NXP 74ABT16543BB,518 is a high-performance BiCMOS 16-bit registered transceiver housed in a 52-lead QFP package. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an ambient temperature range of -40 °C to +85 °C. The device features two sets of D-type latches for temporary data storage with independent control inputs for each direction. Propagation delays are typically 2.5 ns from input to output and 3.1 ns from latch enable to output at 5 V. Outputs provide a sink current capability of 64 mA and a source current of -32 mA.
