CD74HC123PWRE4

Multivibrators Overview

The CD74HC123PWRE4 is a dual retriggerable monostable multivibrator manufactured by Texas Instruments. It belongs to the HC logic family and operates within a supply voltage range of 2 V to 6 V. The device features two independent circuits in a TSSOP-16 package. Key electrical parameters include a maximum propagation delay of 320 ns, a maximum static power supply current of 8 uA, and output drive capabilities of 5.2 mA for both high and low states. It supports operation temperatures from -55 °C to +125 °C.

Multivibrators Feature Summary

• Dual retriggerable monostable multivibrator configuration
• High-speed CMOS technology with balanced outputs
• Positive input clamp diode protection

Multivibrators Applications

• Pulse timing circuits
• Frequency division
• Timing delays

Multivibrators Procurement Notes

Verify the specific suffix 'E4' indicates lead-free compliance as per manufacturer documentation. Confirm the TSSOP-16 package type matches the design requirements. Ensure the operating temperature range meets the environmental specifications of the target application. Cross-reference the datasheet revision to confirm parameter consistency.

Multivibrators Selection Notes

Select this component when a dual-channel retriggerable monostable solution is required in a surface-mount format. The HC series offers compatibility with standard CMOS logic levels. Consider the propagation delay characteristics for signal integrity. Verify that the 2V to 6V supply range aligns with the system power architecture.

Multivibrators Part Context

This part is an enhanced version of the CD74HC123 series, specifically denoted by the 'E4' suffix which typically signifies lead-free packaging. It shares functional similarities with other devices in the 74HC123 family but is distinguished by its specific manufacturing compliance and package variant. It serves as a direct replacement for non-E4 variants where lead-free processing is mandated.

Multivibrators Replacement Considerations

The CD74HC123PWR is a compatible alternative without the E4 suffix. Other family members like CD74HC123MT offer different packaging options.
