SN74LVC373DW

Latches Overview

The SN74LVC373DW is an octal transparent D-type latch featuring three-state outputs, manufactured by Texas Instruments. It operates within a supply voltage range of 1.65 V to 3.6 V and utilizes the LVC logic series for low-voltage CMOS performance. The device provides eight D-type latches with independent data inputs and common clock and output enable controls. It is housed in a 20-pin SOIC package designed for surface-mount applications. Key electrical characteristics include propagation delays of 7.8 ns at 2.7 V and 6.8 ns at 3.3 V, with a maximum static current of 10 µA. Output drive capabilities support 32 mA low-level and -24 mA high-level currents.

• Octal transparent D-type latch architecture with three-state outputs
• Low-voltage operation compatible with 1.65 V to 3.6 V power supplies
• High noise immunity and robust output drive strength
• Supports local termination and reverse-drive protection via Ioff

Latches Applications

• Buffer registers and working registers
• I/O port expansion
• Bidirectional bus drivers
• Memory addressing

Latches Procurement Notes

Verify the specific suffix against official documentation to confirm package type and temperature rating. Ensure compatibility with system voltage levels and signal integrity requirements. Confirm RoHS compliance status through manufacturer datasheets. Validate pinout alignment with PCB layout specifications before integration.

Latches Selection Notes

Select this component for designs requiring multiple parallel data storage elements with tri-state control. Consider the LVC series benefits for low-power applications operating below 3.3 V. Evaluate propagation delay specifications against system timing constraints. Ensure thermal management aligns with the specified operating temperature range.

Latches Part Context

This part belongs to the SN74LVC373A family of octal latches from Texas Instruments. It shares functional similarities with other LVC series devices but offers specific voltage and speed characteristics tailored for modern low-voltage digital systems. The DW suffix indicates a standard SOIC-20 package configuration suitable for general-purpose surface-mount assembly.

Latches Replacement Considerations

SN74LVC373ADWR: Reel-packaged variant of the same logical function and package footprint. SN74LVC373APW: TSSOP-20 package alternative with identical electrical characteristics. SN74LVC373AMDBREP: SSOP-20 enhanced product version.
