CD4044BEE4

Latches Overview

The CD4044BEE4 is a CMOS Quad R/S Latch from the Texas Instruments 4000B series, housed in a 16-lead PDIP package. It operates within a supply voltage range of 3 V to 18 V and supports 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. The device features a maximum static current of 20 uA and a maximum power supply current of 40 nA. Output drive capabilities include a low-level output current of 32 mA and a high-level output current of -4.2 mA.

Latches Feature Summary

• Contains four independent R/S latch circuits with non-inverting outputs.
• Operates across a wide supply voltage range suitable for various logic families.
• Designed for through-hole mounting on printed circuit boards.

Latches Applications

• Data storage and buffering applications
• State holding in digital control systems
• Input debouncing circuits

Latches Procurement Notes

Verify that the component matches the specific CD4044BEE4 designation, ensuring it corresponds to the active PDIP package variant rather than obsolete or alternative packaging options. Confirm RoHS compliance status as indicated by the E4 suffix. Ensure the supplier provides documentation verifying the lead finish and moisture sensitivity level ratings consistent with Texas Instruments specifications.

Latches Selection Notes

Select this component when a quad latch configuration is required in a through-hole design. Consider the propagation delay characteristics relative to the system clock speed. Verify that the input voltage levels are compatible with the driving logic family. Evaluate the thermal requirements against the specified operating temperature range for the intended environment.

Latches Part Context

This part belongs to the CD4044B family of quad R/S latches manufactured by Texas Instruments. It is part of the broader 4000B series of CMOS logic devices. The device is distinct from other variants such as the CD4043B which offers tri-state outputs. It serves as a fundamental building block for sequential logic circuits requiring memory elements.

Latches Replacement Considerations

CD4044BE is listed as an equivalent active production part in the same PDIP package.
