DM74AS373WMX

Latches Overview

The DM74AS373WMX is an 8-bit D-type transparent latch from the 74AS series, manufactured by Fairchild Semiconductor. It features a single function with true output polarity and tri-state outputs designed for driving highly capacitive or low-impedance loads. The device operates within a voltage range of 4.5V to 5.5V and supports a load capacitance of 50 pF. It is housed in a 20-pin SOIC plastic package and functions across a temperature range of -40°C to 85°C.

Latches Feature Summary

• Features totem-pole 3-state outputs specifically engineered for high capacitive or low-impedance driving requirements.

Latches Applications

• Register applications requiring high-speed data storage

Latches Procurement Notes

Verify component authenticity through official Fairchild Semiconductor channels or authorized distributors. Confirm the specific suffix matches the required operating temperature range and package variant. Check for RoHS compliance status as indicated in official documentation, noting that some records indicate non-compliance. Ensure the part number corresponds to the active or obsolete status relevant to your supply chain needs.

Latches Selection Notes

Select this component when designing systems requiring 8-bit latching with high-drive capability. The AS series offers faster performance compared to standard HCT variants. Ensure the design accommodates the 4.5V to 5.5V supply voltage. Verify that the 20-SOIC package fits the PCB layout constraints and thermal management requirements for the intended operating environment.

Latches Part Context

This part belongs to the 74AS logic family, known for advanced Schottky technology providing high speed. It serves as a register component in digital circuits. Similar parts include the MM74HCT573WMX, which shares the 8-bit latch functionality but differs in series characteristics and drive strength specifications.
