CD4043BPWG4

Latches Overview

The CD4043BPWG4 is a CMOS quad NOR R/S latch with three-state outputs manufactured by Texas Instruments. It operates within a supply voltage range of 3 V to 18 V and functions across an extended temperature range from -55 °C to +125 °C. The component utilizes a 16-pin Thin Shrink Small-Outline Package (TSSOP) designed for surface-mount technology. As part of the 4000B series, it provides four independent latches in a single integrated circuit.

Latches Feature Summary

• Integrates four independent NOR-type R/S latches within a single package
• Features three-state outputs allowing direct bus connection without external buffers
• Operates reliably across industrial temperature ranges from -55 °C to +125 °C

Latches Applications

• Data storage applications requiring temporary retention of binary information
• Bus interface circuits utilizing tri-state logic for signal isolation
• Digital control systems employing NOR-based set-reset logic

Latches Procurement Notes

Verify the specific suffix 'G4' indicates lead-free composition and RoHS compliance during procurement. Confirm the TSSOP-16 package dimensions match the target PCB footprint. Ensure the operating environment remains within the specified -55 °C to +125 °C thermal limits to maintain device reliability and electrical characteristics.

Latches Selection Notes

Select this component when a compact solution for multiple latches with bus-compatible outputs is required. The TSSOP package offers space efficiency compared to traditional DIP formats. Consider the 3V to 18V supply range compatibility with existing system power rails before finalizing the design integration.

Latches Part Context

This device belongs to the CD4000B series of CMOS digital logic integrated circuits. It serves as a fundamental building block for sequential logic designs. The component is widely used in general-purpose digital electronics where reliable data latching and bus interfacing are necessary.

Latches Replacement Considerations

The CD4043BDW is a documented alternative offering identical logical functionality in a SOIC-16 package. Verify pinout compatibility and physical footprint differences when substituting between TSSOP and SOIC packages.
