CD4508BE

Latches Overview

The CD4508BE is a CMOS dual 4-bit latch manufactured by Texas Instruments. It operates within a supply voltage range of 3 V to 18 V and features a propagation delay of 260 ns at 5 V, 140 ns at 10 V, and 100 ns at 15 V. The device draws a static current of 100 uA and provides a low-level output current of 32 mA with a high-level output current of -4.2 mA. It is housed in a 24-pin wide DIP package and functions as a non-inverting latch.

Latches Feature Summary

• Dual independent 4-bit latching circuits for digital data storage
• CMOS technology ensuring low power consumption
• Wide operating voltage range supporting diverse logic levels

Latches Applications

• Digital signal latching
• Data storage applications
• Parallel-to-serial conversion interfaces

Latches Procurement Notes

Verify the specific suffix 'BE' corresponds to the 24-pin wide DIP package configuration. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor declarations. Ensure the ordering part number matches the required lead time and availability constraints before finalizing procurement orders.

Latches Selection Notes

Select this component when a dual 4-bit transparent latch is required in a through-hole DIP format. Consider the 3 V to 18 V supply range compatibility with existing system voltages. Evaluate the 260 ns propagation delay at 5 V against system timing requirements to ensure adequate performance margins for the intended application speed.

Latches Part Context

This component belongs to the 4500 series of CMOS logic devices. It serves as a fundamental building block for sequential logic circuits requiring parallel data capture. The dual architecture allows for efficient handling of two separate 4-bit data streams within a single integrated circuit package.

Latches Replacement Considerations

CD4508BEE4 is a verified equivalent part number offering identical electrical characteristics and pinout compatibility.
