CD4044BF

Latches Overview

The CD4044BF is a quad R/S latch manufactured by Texas Instruments, belonging to the 4000 series of CMOS logic devices. It features four independent latches within a single integrated circuit. The device is housed in a 16-lead hermetic dual-in-line ceramic package (CDIP), specifically designated by the F suffix. This packaging variant is designed for high-reliability applications requiring robust environmental protection and durability.

Latches Feature Summary

• Contains four independent R/S latch circuits for data storage
• Utilizes CMOS technology for low power consumption
• Hermetically sealed ceramic construction for harsh environments

Latches Applications

• Military and defense electronic systems
• High-reliability aerospace instrumentation
• Industrial control systems requiring radiation or environmental hardness

Latches Procurement Notes

Verify that the specific order matches the CD4044BF part number to ensure receipt of the hermetic ceramic package rather than plastic or surface-mount variants. Confirm RoHS compliance status as ceramic packages may have different material specifications compared to standard catalog versions. Check current production status with the manufacturer to ensure availability for new designs.

Latches Selection Notes

Select this component when hermetic sealing is mandatory for the application environment. The ceramic package provides superior protection against moisture and contaminants compared to plastic equivalents. Ensure the design accommodates through-hole mounting requirements associated with the DIP form factor.

Latches Part Context

This device is part of the broader CD4044B family from Texas Instruments. While other variants exist in plastic DIP, SOIC, and TSSOP packages, the BF designation specifically identifies the hermetic ceramic version. It shares functional compatibility with non-hermetic counterparts but offers enhanced physical durability.

Latches Replacement Considerations

Direct substitutes include the CD4044BF3A, which shares the same hermetic ceramic package type. Other CD4044B variants require package adaptation.
