74FCT162543ATPACT

Buffers, Drivers, Receivers, Transceivers Overview

The Texas Instruments 74FCT162543ATPACT is a 16-bit registered bus transceiver belonging to the FCT logic series. It features two independent 8-bit circuits with non-inverting true outputs and three-state capability. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports TTL input and output levels. Key electrical parameters include a propagation delay of 6.5 ns, low-level output current of 64 mA, and high-level output current of -32 mA. It is housed in a TSSOP-56 package and functions across an industrial temperature range from -40°C to +85°C.
