SN74AS652DW

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AS652DW is an octal bus transceiver and register from the AS logic series, manufactured by Texas Instruments. It features true outputs with three-state capability and operates within a supply voltage range of 4.5 V to 5.5 V. The device provides a propagation delay of 9 ns and supports TTL input and output levels. It delivers a low-level output current of 48 mA and a high-level output current of -15 mA. Packaged in a 24-pin SOIC format, it functions as a bidirectional transceiver suitable for industrial temperature ranges.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Octal registered transceiver architecture supporting multiplexed transmission of registered or real-time data
• Three-state outputs enable direct connection to system buses without additional drivers
• Independent control logic allows flexible direction management for bidirectional data flow

Buffers, Drivers, Receivers, Transceivers Applications

• Multiplexed data transmission systems requiring registered data handling
• High-speed bus architectures utilizing TTL-compatible signaling
• Industrial control interfaces operating within standard commercial temperature limits

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package variant against official datasheets, as suffixes may indicate different thermal or mechanical specifications. Confirm RoHS compliance status directly with the manufacturer documentation. Ensure the ordering code matches the required pinout and lead finish. Cross-reference the component revision history for any assembly changes that might affect compatibility.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when high-speed registered bus transfer is required alongside true output polarity. Compare propagation delays and drive strengths against alternative AS series devices. Verify that the 48 mA low-level sink capability meets the load requirements of the destination circuitry. Ensure the SOIC-24 footprint aligns with the existing PCB layout constraints.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the Texas Instruments SN74AS family, known for advanced Schottky technology providing high speed. It serves as a registered bus transceiver, distinct from non-registered variants like the SN74AS646. The device integrates latching functionality to hold data during bus transitions, making it suitable for complex digital communication protocols.
