SN74ALS845DW

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ALS845DW is an octal bus-interface D-type latch manufactured by Texas Instruments in the ALS logic series. It features nine independent D-type latches with three-state outputs housed in a 24-pin SOIC package. The device supports true output polarity and includes dedicated clear and preset functions for direct control of latch states. Designed for high-speed digital applications, it operates within a standard voltage range and provides robust drive capabilities suitable for bus-oriented memory and register architectures.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify component authenticity against Texas Instruments specifications. Confirm the SOIC-24 package type matches design requirements. Ensure compliance with project environmental standards as the device may not meet current RoHS directives. Validate electrical parameters against the official datasheet before integration into critical systems.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when nine synchronized latches with tri-state capability are required. The ALS series offers improved speed over standard TTL while maintaining compatible logic levels. Consider the SOIC-24 footprint for surface-mount assembly constraints. Evaluate power consumption and thermal dissipation needs relative to the specific application environment.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the Texas Instruments SN74ALS family of advanced low-power Schottky logic devices. The SN74ALS845 specifically addresses the need for octal latching with bus isolation. It complements other ALS drivers and transceivers in system designs requiring reliable data holding and controlled output impedance.
