SN74F543DW

Buffers, Drivers, Receivers, Transceivers Overview

The SN74F543DW is an octal registered transceiver from the Texas Instruments SN74F logic family, designed for bidirectional data transmission. It features eight non-inverting channels with three-state outputs housed in a 24-pin SOIC package. 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 specifications include a maximum propagation delay of 7.5 ns, a low-level output current capability of 64 mA, and a high-level output current of -15 mA. It functions reliably across an operating temperature range of 0°C to +70°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'DW' corresponds to the SOIC-24 package and tape-and-reel or cut-tape availability as required by your assembly process. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure that the 4.5V to 5.5V operating voltage aligns with your target power supply rails. Check for any updated lifecycle notices or obsolescence warnings directly from Texas Instruments before finalizing procurement plans.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring high-speed data transfer with registered storage capabilities at standard 5V logic levels. The SN74F series offers faster switching speeds compared to standard 74LS counterparts but consumes more power. Consider the 64mA sink current capability for driving moderate capacitive loads on data buses. Evaluate thermal dissipation requirements given the F-series power characteristics in enclosed environments.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74F543 series of octal registered transceivers manufactured by Texas Instruments. It is part of the broader SN74xx logic family, specifically utilizing Fast (F) technology for improved speed performance. The device serves as a critical interface element between processors and peripheral devices, ensuring data integrity through internal latching mechanisms while providing necessary signal buffering for complex digital architectures.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

SN74F543DWR shares identical electrical characteristics and pinout configuration, differing only in the SOIC-24 package variant designation. SN74BCT543DW offers similar functionality but utilizes BCT technology with potentially different drive strengths and power consumption profiles. Verify pin compatibility and voltage tolerances before substituting with alternative logic families.
