CD4044BPWE4

Latches Overview

The CD4044BPWE4 is a CMOS quad R/S latch manufactured by Texas Instruments, belonging to the 4000B logic series. It features four independent non-inverting latches in a 16-pin Thin Shrink Small-Outline (TSSOP) package. The device operates within a supply voltage range of 3 V to 18 V and supports an operating temperature range from -55 °C to +125 °C. Propagation delay varies with voltage: 300 ns at 5 V, 140 ns at 10 V, and 100 ns at 15 V. Static current is typically 20 µA, with maximum power supply current of 40 nA. Low-level output current reaches 32 mA, while high-level output current is -4.2 mA.

Latches Procurement Notes

Verify the component matches the specific TSSOP-16 package and lead-free designation indicated by the E4 suffix. Confirm that the supplier provides documentation confirming compliance with RoHS standards. Ensure the part number corresponds exactly to the Texas Instruments manufacturing origin to avoid counterfeit risks. Check for any specific handling requirements related to moisture sensitivity during storage and assembly processes.

Latches Selection Notes

Select this component when a quad latch configuration is required in a compact surface-mount format. The wide voltage range makes it suitable for systems operating between 3 V and 18 V. Consider the propagation delays when designing timing-critical paths. The extended temperature range is advantageous for industrial or automotive applications where environmental stability is critical.

Latches Part Context

This part belongs to the CD4000B series of CMOS logic devices, which are widely used in general-purpose digital electronics. The CD4044B variant specifically provides R/S latch functionality. The BPWE4 suffix indicates a plastic TSSOP package with lead-free terminals, aligning with modern environmental regulations and automated assembly processes common in contemporary electronics manufacturing.

Latches Replacement Considerations

Compatible alternatives include the CD4043B series for tri-state outputs or other quad latches like the CD40194 if shift register functionality is needed. Verify pin compatibility and electrical characteristics before substitution. Cross-reference with manufacturer datasheets to ensure functional equivalence in terms of voltage ranges and package dimensions.
