74ABT16543CSSC

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74ABT16543CSSC is a 16-bit registered transceiver with 3-state outputs, housed in a 56-lead Shrink Small Outline Package (SSOP). It operates within a supply voltage range of +4.5V to +5.5V 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, allowing bidirectional data flow between A and B ports. Each byte has separate control inputs, enabling independent operation as two 8-bit transceivers or one 16-bit unit. Outputs provide current sourcing capability of 32 mA and sinking capability of 64 mA.

Buffers, Drivers, Receivers, Transceivers FAQ

What is the function of the CEABn and OEBAn inputs?

CEABn is the A-to-B Enable Input (Active LOW), and OEBAn is the B-to-A Output Enable Input (Active LOW). These controls manage the direction and enablement of data flow.

How does the device handle data storage?

It contains two sets of D-type latches that temporarily store data flowing in either direction. Separate Latch Enable inputs allow independent control of storing data.
