CD4724BPWR

Latches Overview

The CD4724BPWR is an addressable latch integrated circuit manufactured by Texas Instruments, belonging to the 4000B series. It features a single D-type latch circuit housed in a 16-TSSOP surface-mount package. 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. Key electrical specifications include a propagation delay of 50ns and output currents of 6.8mA for both high and low states. The component is RoHS compliant and has a moisture sensitivity level of 1.

Latches Feature Summary

• Functions as an 8-bit addressable latch with three address inputs (A0-A2) and one data input (D).
• Capable of acting as a 1-of-8 demultiplexer when clear and enable conditions are met.
• Provides standard output types with high noise immunity characteristics.

Latches Applications

• Data storage applications requiring selective bit addressing.
• Demultiplexing circuits utilizing the addressable latch functionality.
• General-purpose logic interfacing within the 4000B CMOS family.

Latches Procurement Notes

This component is officially obsolete and no longer manufactured by Texas Instruments. Procurement must rely on secondary market distributors or surplus stock providers. Verify lot dates and authenticity carefully, as original production has ceased. Ensure compatibility with existing designs before sourcing from non-primary channels.

Latches Selection Notes

Select this part only if legacy 4000B series compatibility is required. Consider the CD4099BPWR as a similar alternative currently available from the manufacturer. Evaluate whether the specific addressable latch architecture is necessary or if standard latches suffice. Confirm that the 16-TSSOP package fits the target PCB layout constraints.

Latches Part Context

The CD4724B is part of the broader 4000B series of CMOS logic devices produced by Texas Instruments. This series is known for wide voltage operation and compatibility with earlier TTL standards. The BPWR suffix indicates the specific tape-and-reel packaging variant in the TSSOP-16 form factor, designed for automated surface-mount assembly processes.

Latches Replacement Considerations

The CD4099BPWR is listed as a similar replacement option by distributors. Verify functional equivalence regarding pinout and logic behavior before substitution. No other direct substitutes are confirmed in the provided documentation.
