CD4044BPWR

Latches Overview

The CD4044BPWR is a CMOS quad R/S latch from the Texas Instruments 4000B series, housed in a 16-pin TSSOP 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. The device features four independent latches with non-inverting outputs and a maximum propagation delay of 50 ns. It draws a maximum supply current of 40 nA and provides output currents of 6.8 mA for both high and low states.

Latches Feature Summary

• Contains four independent R/S latch circuits within a single integrated circuit
• Provides non-inverting outputs for direct signal interfacing
• Operates reliably across extended industrial temperature ranges

Latches Applications

• Data storage and buffering in digital logic systems
• State holding elements in sequential logic circuits
• Input debouncing applications for mechanical switches

Latches Procurement Notes

Verify the specific suffix BPWR indicates the TSSOP-16 surface-mount package variant. Confirm RoHS compliance status and ensure the component matches the required lead-free specifications for your assembly process. Cross-reference the manufacturer part number against official distributor catalogs to validate authenticity and current production status before ordering.

Latches Selection Notes

Select this component when a compact surface-mount solution for multiple latching functions is required. The TSSOP package offers space efficiency compared to through-hole alternatives. Ensure the design accommodates the specified voltage and temperature limits. Consider the 50 ns propagation delay for timing constraints in the target application circuit.

Latches Part Context

This component belongs to the CD4000B series of CMOS logic devices, widely used for general-purpose digital applications. The CD4044B type specifically provides quad R/S latch functionality. The 'PWR' suffix denotes the plastic small-outline package variant manufactured by Texas Instruments, distinguishing it from DIP or SOIC versions.

Latches Replacement Considerations

Compatible substitutes include the CD4043BPWR (NOR-based latch) and CD4044BDWR (SOIC package). Verify pin compatibility and logical equivalence when substituting. The CD4043BPWR requires attention to its NOR gate input structure versus the NAND-based R/S inputs of the CD4044.
