CD4044BDWRE4

Latches Overview

The CD4044BDWRE4 is a CMOS Quad R/S Latch from the Texas Instruments 4000B series, housed in a 16-pin SOIC package. It features non-inverting outputs and operates within a supply voltage range of 3 V to 18 V. The device supports through-hole or surface-mount installation with an operating temperature range of -55 °C to +125 °C. Propagation delay is specified at 300 ns at 5 V, 140 ns at 10 V, and 100 ns at 15 V. Static current is typically 20 uA, with low-level output current of 32 mA and high-level output current of -4.2 mA.

Latches Feature Summary

• Quad R/S latch configuration with independent set and reset inputs for each channel
• Non-inverting output polarity suitable for positive logic systems
• Wide operating voltage range supporting diverse power supply requirements
• Extended industrial temperature rating for reliable performance in harsh environments

Latches Applications

• Data storage elements in digital circuits
• Control systems requiring state retention
• Signal synchronization applications
• General-purpose digital logic interfacing

Latches Procurement Notes

Verify the E4 suffix indicates lead-free composition and RoHS compliance per manufacturer standards. Confirm the BDWR designation corresponds to the specific SOIC-16 tape and reel packaging format. Ensure the component matches the 4000B series specifications for voltage and temperature ratings before integration into final designs.

Latches Selection Notes

Select this component when non-inverting latch functionality is required for positive logic applications. Compare against the CD4043B series if tri-state outputs are necessary instead of standard CMOS outputs. Consider the PDIP variant if through-hole mounting is preferred over surface-mount technology for the same logical function.

Latches Part Context

This part belongs to the Texas Instruments CD4000B series of CMOS logic devices. It serves as the non-inverting counterpart to the CD4043B NOR latch. The device is designed to meet JEDEC temporary standard No. 13B for B-series CMOS device descriptions, ensuring compatibility with other components in the same logic family.

Latches Replacement Considerations

The CD4044BDW is the non-E4 equivalent version. For tri-state output requirements, the CD4043BDWR is a functional alternative within the same package.
