SN74AS575DW

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AS575DW is an octal D-type edge-triggered flip-flop with three-state outputs manufactured by Texas Instruments. It belongs to the AS (Advanced Schottky) logic series, providing high-speed performance suitable for demanding digital applications. The device features a true output configuration and operates within a supply voltage range of 4.5 V to 5.5 V. It is housed in a 24-pin Small Outline Package (SOIC), designated as PDSO24, designed for surface-mount technology. The component supports TTL input levels and includes dedicated clock and output enable controls for precise data management.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify current availability status as this component may be discontinued or subject to limited production runs. Confirm package integrity and pin alignment against the SOIC-24 specification during incoming inspection. Ensure static-sensitive handling protocols are followed due to CMOS-compatible input structures. Cross-reference manufacturer documentation for any recent design changes or lifecycle notifications prior to final procurement authorization.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when advanced Schottky speed is required alongside tri-state bus compatibility. Evaluate thermal performance under maximum load conditions given the bipolar nature of the AS series. Compare propagation delays against system timing requirements to ensure signal integrity. Consider pinout compatibility with existing PCB layouts utilizing standard 24-pin SOIC footprints.

Buffers, Drivers, Receivers, Transceivers Part Context

This part is part of the SN74AS family, which offers faster switching speeds compared to standard 74S series devices while maintaining similar pinouts. It serves as a functional equivalent to other octal latches but utilizes edge-triggering rather than level-triggering for data capture. The DW suffix specifically denotes the plastic small outline package variant suitable for automated surface-mount assembly processes.
