SNJ54ABT652AFK

Buffers, Drivers, Receivers, Transceivers Overview

The SNJ54ABT652AFK is an octal registered transceiver with 3-state outputs manufactured by Texas Instruments. It utilizes EPIC-IIB BiCMOS design for reduced power dissipation and features high-drive outputs capable of -32-mA IOH and 64-mA IOL. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports clock frequencies up to 125 MHz. It is housed in a 28-pin LCCC (FK) package and is characterized for operation over the military temperature range of -55°C to 125°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify that the specific ordering suffix FK corresponds to the 28-pin LCCC package configuration required for your application. Confirm that the component meets the necessary military specifications, as indicated by the SN54 prefix. Ensure compatibility with the 4.5 V to 5.5 V supply voltage requirements during system integration.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems that require both registered storage and direct bus transparency. The dual output-enable inputs allow flexible control over data flow direction. Consider the high-drive capability for driving heavy capacitive loads or long traces without external buffering.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN54/74ABT652A family of octal registered transceivers. The SN54 variant denotes military-grade qualification, while the SN74 represents commercial grade. Both share identical functional logic but differ in manufacturing standards and operational temperature limits.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the select-control input affect data transfer?

A low select-control input enables real-time data transfer from the bus, while a high input selects stored data from the internal D-type flip-flops for transfer.

What measures prevent glitches during data source transitions?

The circuitry used for select control eliminates typical decoding glitches that occur in multiplexers during the transition between stored and real-time data sources.
