CD4043BPW

Latches Overview

The CD4043BPW is a CMOS quad NOR R/S latch with three-state outputs manufactured by Texas Instruments. It operates within a supply voltage range of 3V to 18V and features an operating temperature range from -55°C to 125°C. The device is housed in a 16-TSSOP package with dimensions of 4.40mm width. Key electrical characteristics include a propagation delay of 50ns and output currents of 6.8mA for both high and low states.

Latches Feature Summary

• Quad configuration providing four independent NOR R/S latches
• Three-state outputs allowing bus-driven applications
• Wide operating voltage range suitable for various logic families
• Extended industrial temperature rating for harsh environments

Latches Applications

• Data storage in digital systems
• Bus-oriented memory structures
• Temporary data holding registers
• Interface circuits requiring tri-state control

Latches Procurement Notes

Verify the specific suffix 'PW' confirms the TSSOP-16 package type when ordering. Ensure compatibility with 3V to 18V supply rails. Confirm RoHS compliance status if required for your assembly process. Check for alternative suffixes like 'PWR' or 'BDW' if different packaging or lead-free options are needed. Validate that the manufacturer is Texas Instruments to ensure specified performance parameters.

Latches Selection Notes

Select this component when a quad latch with tri-state capability is required. Consider the 16-TSSOP package for surface mount applications. Evaluate the 50ns propagation delay against system timing requirements. Ensure the 6.8mA drive current meets load specifications. Verify the -55°C to 125°C temperature range fits the operational environment.
