74ABT16543CSSCX

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74ABT16543CSSCX 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 for independent operation as two 8-bit transceivers or one 16-bit unit. Output drive capabilities include sourcing 32 mA and sinking 64 mA.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Back-to-back registers provide temporary storage for data flowing in either direction.
• Separate latch enable and output enable inputs allow independent control of inputting and outputting.
• High impedance glitch-free bus loading is maintained during the entire power-up and power-down cycle.
• Guaranteed latchup protection ensures robust performance under electrical stress.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the device handle data flow direction?

Data flow is controlled by separate Enable inputs (CEABn and CEBAn). For A-to-B flow, CEABn must be low; for B-to-A flow, CEBAn must be low. Latch Enable inputs determine when data is stored.

What is the purpose of the separate control logic for each byte?

Separate control logic allows the device to function as two independent 8-bit transceivers or a single 16-bit transceiver, providing flexibility in system design and data handling.
