SN74LVC543ADWR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVC543ADWR is an octal registered transceiver from the Texas Instruments LVC logic family, designed for 1.65-V to 3.6-V VCC operation. It features eight non-inverting channels with tri-state outputs in a 24-pin SOIC package. The device supports low-voltage TTL (LVTTL) input and output levels, ensuring compatibility with diverse digital systems. Key electrical parameters include a propagation delay of 8 ns, with low-level and high-level output currents rated at 24 mA and -24 mA respectively. It operates within a temperature range of -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Octal registered transceiver architecture providing data storage and bidirectional bus driving capabilities.
• Tri-state outputs allow connection to multiple devices on a shared bus without signal contention.
• Designed for low-voltage CMOS technology enabling efficient power consumption in portable applications.

Buffers, Drivers, Receivers, Transceivers Applications

• Mobile communications equipment requiring low-power data buffering.
• Consumer electronics utilizing 3.3V or 1.8V logic interfaces.
• Industrial control systems needing isolated bus segments with latched data holding.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'DWR' corresponds to the 24-SOIC package and tape-and-reel shipping configuration. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure voltage supply rails strictly remain within the 1.65-V to 3.6-V operational limits to prevent device damage.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal width with internal registration is required for low-voltage systems. Compare against the SN74LVC541 if unidirectional buffering suffices, or consider the SN74ABT543 for higher drive current needs at 5V. Evaluate the 8 ns propagation delay against system timing constraints to ensure adequate setup and hold times are met.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVC543A series of octal bus transceivers. It complements other LVC family members like the SN74LVC541 by offering registered functionality rather than simple buffering. The device serves as a bridge between different voltage domains while maintaining data integrity through its latch capability.
