4724BDC

Overview

The CD4724BC is an 8-bit addressable latch manufactured by National Semiconductor. It features three address inputs (A0–A2), an active low enable input (E), an active high clear input (CL), a data input (D), and eight outputs (Q0–Q7). Data enters the addressed bit when the enable is low. The device operates with a supply voltage range of 3.0V to 15V.

Feature Summary

• Provides 8-bit addressable latching capability with dedicated control inputs for selective data entry.

Applications

• Data storage in digital systems requiring selective bit access

Procurement Notes

Verify the manufacturer designation, as National Semiconductor assets are managed by Texas Instruments. Confirm the specific suffix indicates the correct package and temperature rating. Ensure the component matches the original National Semiconductor specifications rather than generic equivalents.

Selection Notes

Select this component for applications requiring an 8-bit latch with addressable inputs. Verify that the operating voltage range of 3V to 15V aligns with the system power supply. Check compatibility with the required logic family levels for the address and data inputs.

Part Context

This part belongs to the CD472xB series of addressable latches. The CD4723B variant offers dual 4-bit latching, while the CD4724B provides a single 8-bit configuration. Both share similar control logic structures including common enable and clear inputs for synchronized operation within larger digital circuits.
