SN74F543NT

Buffers, Drivers, Receivers, Transceivers Overview

The SN74F543NT is an octal registered transceiver from the Texas Instruments SN74F logic series, housed in a 20-pin DIP package. It features two sets of D-type latches for temporary data storage and bidirectional flow control. The device provides three-state outputs with TTL-compatible input and output levels. Key electrical parameters include a propagation delay of 7.5 ns, a low-level output current of 64 mA, and a high-level output current of -15 mA. It operates within a supply voltage range of 4.5 V to 5.5 V and supports a commercial temperature range of 0°C to +70°C.
