CD4044BDW

Latches Overview

The CD4044BDW is a CMOS quad NAND R/S latch integrated circuit manufactured by Texas Instruments. It features four independent latches in a 16-pin SOIC package. The device operates within a supply voltage range of 3V to 18V and supports an operating temperature range from -55°C to +125°C. It belongs to the 4000B logic series and provides true output polarity with three-state output characteristics.

Latches Feature Summary

• Contains four independent NAND R/S latch circuits
• Features three-state output capability for bus driving applications
• Operates across a wide industrial temperature range
• Supports standard CMOS logic levels

Latches Applications

• Data storage and buffering in digital systems
• Interface circuits requiring tri-state control
• Industrial control logic modules
• Memory address latching

Latches Procurement Notes

Verify the specific suffix 'DW' indicates the SOIC-16 package variant. Confirm RoHS compliance status as per current manufacturer documentation. Check for obsolescence notices or lifecycle changes before finalizing procurement plans. Ensure compatibility with existing PCB footprints for 16-SOIC components.

Latches Selection Notes

Select this component when a quad latch with tri-state outputs is required. Compare propagation delay specifications against system timing requirements. Verify that the 3V to 18V supply range matches the target application power rails. Consider the 16-SOIC package dimensions for board space constraints.

Latches Part Context

This part belongs to the Texas Instruments CD4000B series of CMOS logic devices. It is functionally related to other latches in the family, such as the CD4042 and CD4043. The CD4044 specifically implements NAND-based R/S logic with added tri-state functionality compared to basic latches.

Latches Replacement Considerations

CD4044BDWR is a reel-pack alternative of the same logical device. CD4043BDW offers similar latch functionality but uses NOR-based inputs instead of NAND.
