CD4043BDRG4

Latches Overview

The CD4043BDRG4 is a quad RS latch integrated circuit manufactured by Texas Instruments, belonging to the 4000B CMOS logic series. It features four independent latches with tri-state outputs and non-inverting polarity. The device operates within a supply voltage range of 3V to 18V and supports a wide operating temperature range from -55°C to +125°C. It is housed in a 16-pin SOIC package with surface mount installation. Key electrical characteristics include a propagation delay of 50ns and output currents of 6.8mA for both high and low states.

Latches Feature Summary

• Contains four independent RS latch circuits with transparent locking mode
• Provides tri-state outputs for bus-oriented applications
• Supports direct set and reset functions without clock dependency

Latches Applications

• Data storage in digital systems
• Bus holding applications
• Interface between different logic families

Latches Procurement Notes

Verify the component authenticity by checking the manufacturer marking and date code against official Texas Instruments documentation. Ensure the package type matches the required 16-SOIC specification. Confirm that the RoHS compliance status aligns with environmental regulations applicable to your region. Cross-reference the part number suffix to ensure it corresponds to the specific tape and reel or tube packaging variant required for your assembly process.

Latches Selection Notes

Select this component when a quad RS latch with tri-state capability is required in a CMOS process. It is suitable for designs needing wide voltage operation and high-temperature stability. Consider the 16-SOIC package dimensions for PCB layout constraints. Verify that the input and output voltage levels are compatible with the rest of the system logic family.

Latches Part Context

This part is part of the CD4000B series of CMOS logic devices, known for their wide operating voltage range and compatibility with various power supplies. The CD4043B variant specifically provides RS latch functionality, distinguishing it from other logic types like flip-flops or buffers within the same series. It is designed for general-purpose digital applications requiring reliable data retention and control.

Latches Replacement Considerations

The CD4044BDR is listed as a parameter-equivalent substitute. Verify pinout and functional compatibility before substitution.
