DM74ALS533WMX

Latches Overview

The DM74ALS533WMX is an octal transparent latch manufactured by Fairchild Semiconductor, belonging to the advanced low-power Schottky (ALS) logic family. It features eight D-type latches with three-state outputs housed in a 20-pin SOIC package. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range from 0°C to +70°C. Key electrical specifications include a propagation delay of 4 ns and output currents of 2.6 mA for high state and 24 mA for low state.

Latches Feature Summary

• Contains eight independent D-type transparent latches providing data storage capability.
• Features three-state outputs allowing direct connection to system buses without external buffers.
• Utilizes advanced low-power Schottky technology to achieve improved switching speeds while maintaining reduced power consumption.

Latches Applications

• Registering data in microprocessor-based systems
• Temporary storage in digital signal processing applications
• Data buffering between asynchronous components

Latches Procurement Notes

Verify component authenticity through official manufacturer channels or authorized distributors. Confirm that the part number suffix matches the specific package variant required for your design. Check for RoHS compliance status if environmental regulations apply to your manufacturing process. Ensure proper handling procedures are followed due to surface-mount packaging requirements.

Latches Selection Notes

Select this component when designing circuits requiring multiple parallel data registers with bus-compatible outputs. Consider the ALS series characteristics for applications needing faster switching than standard LS logic but lower power than older Schottky types. Evaluate the 20-SOIC package dimensions against available board space constraints before finalizing the schematic.

Latches Part Context

This device is part of the DM74ALS533 series, which represents a line of octal latches designed for high-speed digital logic applications. The ALS series offers performance improvements over previous generations, balancing speed and power efficiency. Fairchild Semiconductor developed this component to meet industry standards for reliable data retention in complex electronic systems.

Latches Replacement Considerations

SN74ALS533ADW and SN74ALS533ANSR are confirmed substitutes from Texas Instruments. Verify pin compatibility and electrical parameters before implementation.
