74ALVC373PW,118

Latches Overview

The 74ALVC373PW,118 is an octal D-type transparent latch manufactured by Nexperia USA Inc. It belongs to the ALVC logic family and features tri-state outputs in a 20-pin TSSOP package. The device operates with a supply voltage range of 1.2 V to 3.6 V. Key electrical parameters include a propagation delay of 5.5 ns at 3.3 V and a high-level output current of -24 mA. It supports a maximum operating temperature of +125 °C and includes low static power consumption characteristics typical of CMOS technology.

Latches Feature Summary

• Octal configuration providing eight independent D-type transparent latches within a single integrated circuit.
• Tri-state output capability allowing multiple devices to share bus lines without interference.
• Non-inverting logic polarity ensuring direct signal transmission from input to output when enabled.

Latches Applications

• Data storage in digital communication systems
• Buffering for microprocessor address and data buses
• Register files in embedded controller architectures

Latches Procurement Notes

Verify component authenticity through official Nexperia channels or authorized distributors. Confirm package integrity and pin alignment upon receipt. Ensure storage conditions comply with moisture sensitivity levels specified in the datasheet. Check for obsolescence notices as lifecycle status may affect long-term availability. Validate part markings against official documentation to prevent counterfeit substitution.

Latches Selection Notes

Select this component when designing systems requiring octal latching with tri-state control. Compare propagation delays and drive currents against system timing requirements. Consider the 1.2 V to 3.6 V supply range for compatibility with low-voltage logic families. Evaluate thermal performance given the +125 °C maximum junction temperature rating. Assess package constraints relative to PCB layout density and soldering capabilities.

Latches Part Context

This part is part of the 74ALVC series, designed for low-voltage applications. It shares functional similarities with other octal latches like the 74LV373 but offers faster switching speeds due to the ALVC technology. The TSSOP-20 package provides a compact footprint suitable for space-constrained designs. It serves as a standard solution for parallel data retention in modern digital electronics.

Latches Replacement Considerations

Direct substitutes include the 74ALVC373PW-T. Verify pinout compatibility before replacing. Cross-reference specifications for voltage ranges and output drive strengths to ensure functional equivalence in the target application.
