CD4724BE

Latches Overview

The CD4724BE is an 8-bit addressable latch from the Texas Instruments CD4000B series, housed in a 16-pin PDIP package. It operates on a supply voltage range of 3 V to 18 V and supports a wide temperature range from -55 °C to +125 °C. The device features non-inverting outputs with a low-level output current of 32 mA and a high-level output current of -4.2 mA. Propagation delay varies with voltage: 400 ns at 5 V, 150 ns at 10 V, and 100 ns at 15 V.

Latches Feature Summary

• Provides 8-bit data storage with individual address selection for each bit.
• Acts as a 1-of-8 demultiplexer when configured appropriately.
• Features standard CMOS outputs capable of driving significant loads.

Latches Applications

• Data storage applications requiring parallel access to specific bits.
• Demultiplexing circuits utilizing address lines for signal routing.
• Industrial control systems operating within extended temperature ranges.

Latches Procurement Notes

Verify the exact suffix against official documentation, as 'BE' may indicate legacy or obsolete status compared to modern equivalents like 'BPWR'. Confirm package type (PDIP vs TSSOP) matches design requirements. Check RoHS compliance details in the latest datasheet. Ensure availability through authorized channels due to potential discontinuation.

Latches Selection Notes

Select this component for designs requiring robust CMOS latching with high drive capability. Consider the PDIP package for through-hole prototyping or legacy board compatibility. Evaluate propagation delays against system clock speeds. Verify power supply stability within the 3 V to 18 V range for reliable operation across all environmental conditions.

Latches Part Context

Part of the CD4000B series, known for wide voltage operation and industrial-grade reliability. The CD4724B specifically addresses multi-bit storage needs where selective bit access is critical. It serves as a bridge between serial input and parallel output architectures in older digital logic designs.

Latches Replacement Considerations

CD4099BPWR is listed as a similar replacement option by distributors. Verify functional equivalence and pinout compatibility before substitution. Other CD4000B series latches may offer different packaging or updated manufacturing processes.

Latches FAQ

What is the maximum low-level output current?

The maximum low-level output current is 32 mA.

Does the device support bidirectional data flow?

No, it functions as a latch/demultiplexer with unidirectional data flow from input to addressed outputs.
