CD4043BEE4

Latches Overview

The CD4043BEE4 is a quad R/S latch manufactured by Texas Instruments, belonging to the 4000 series of CMOS logic devices. It features four independent latches with set and reset inputs, housed in a 16-lead Plastic Dual In-Line (PDIP) package. The device operates within a supply voltage range of 3 V to 18 V and supports an operating temperature range from -55°C to +125°C. Key electrical characteristics include a maximum static current of 20 µA, a low-level output current of 32 mA, and a high-level output current of -4.2 mA. Propagation delay varies with voltage: 300 ns at 5 V, 140 ns at 10 V, and 100 ns at 15 V.

Latches Feature Summary

• Contains four independent R/S latch circuits for data storage applications
• Operates on standard CMOS technology compatible with the 4000 series logic family
• Provides non-inverting outputs for direct signal interfacing

Latches Applications

• Data storage and buffering in digital systems
• State holding in sequential logic circuits
• Interface control for memory address latching

Latches Procurement Notes

Verify the specific ordering suffix 'E4' confirms the lead-free (RoHS compliant) status and NIPDAU lead finish as documented in the manufacturer's packaging addendum. Confirm the PDIP-16 package type matches the required through-hole mounting style for the target PCB design. Ensure the active production status aligns with long-term availability requirements for the intended application lifecycle.

Latches Selection Notes

Select this component when a quad latch configuration is required within a single integrated circuit. The wide supply voltage range allows compatibility with various logic levels. Consider the PDIP-16 package constraints regarding board space and thermal dissipation compared to surface-mount alternatives like SOIC or TSSOP variants available within the same logic family.

Latches Part Context

This part belongs to the CD4043B/CD4044B family of quad R/S latches produced by Texas Instruments. The CD4043B variant specifically offers non-inverting outputs, distinguishing it from the CD4044B which provides inverted outputs. Both share identical pinouts and electrical specifications, allowing for functional substitution based solely on output polarity requirements.

Latches Replacement Considerations

The CD4043BE serves as the non-RoHS equivalent. For inverted output functionality, the CD4044BEE4 is the direct alternative. Surface-mount replacements include CD4043BDWRE4 and CD4043BPWRG4.
