CD4044BPWG4

Latches Overview

The CD4044BPWG4 is a quad R/S latch manufactured by Texas Instruments, belonging to the 4000B series of CMOS logic devices. It features four independent non-inverting latches in a single package. The device operates within a supply voltage range of 3 V to 18 V and supports a maximum input frequency of 2.4 MHz. Propagation delay varies with voltage: 300 ns at 5 V, 140 ns at 10 V, and 100 ns at 15 V. It has a static current of 20 uA and output currents of 32 mA (low) and -4.2 mA (high). Operating temperatures range from -55°C to +125°C. The component is housed in a 16-pin TSSOP surface-mount package.

Latches Feature Summary

• Contains four independent non-inverting R/S latch circuits for data storage applications.
• CMOS technology ensures low static power consumption and high noise immunity.
• Wide operating voltage range allows compatibility with various digital systems.
• Industrial temperature rating supports operation in extreme environmental conditions.

Latches Applications

• Data storage in digital logic circuits
• Shift register construction
• Memory buffer interfaces

Latches Procurement Notes

Verify the specific suffix 'G4' indicates lead-free and RoHS compliance status as per manufacturer documentation. Confirm the TSSOP-16 package dimensions match PCB footprint requirements. Ensure the industrial temperature grade (-55°C to +125°C) meets system thermal specifications. Cross-reference the datasheet revision to confirm pinout consistency with existing designs.

Latches Selection Notes

Select this component when multiple independent latching functions are required in a compact surface-mount form factor. The wide voltage range suits both low-power and standard logic interfaces. Consider the propagation delay characteristics relative to clock speeds. Verify that the TSSOP package is suitable for the assembly process compared to through-hole alternatives like the PDIP variant.

Latches Part Context

This part is part of the CD4000B series, a family of complementary metal-oxide-semiconductor (CMOS) logic devices. The CD4044B specifically provides quad R/S latch functionality. The 'P' denotes the plastic TSSOP package, while 'W' typically refers to the tape and reel or tube packaging configuration depending on the specific distributor coding, though the base device remains the same. It serves as a fundamental building block for sequential logic design.

Latches Replacement Considerations

CD4044BE is a direct functional equivalent in a PDIP-16 through-hole package. CD4044BDRG4 offers the same logic function in an SOIC-16 surface-mount package. Verify pin compatibility and package dimensions before substituting to ensure mechanical fit.
