CD74HC4538PWRG4

Multivibrators Overview

The CD74HC4538PWRG4 is a high-speed CMOS dual retriggerable precision monostable multivibrator manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 6 V and features Schmitt trigger inputs for noise immunity. The device provides two independent circuits in a 16-TSSOP package, with a maximum static power supply current of 8 uA. Output drive capabilities include low-level and high-level currents of 5.2 mA. It supports operation temperatures from -55°C to +125°C.

Multivibrators Feature Summary

• Dual retriggerable precision monostable multivibrator architecture
• Schmitt trigger inputs on A and B channels for noise filtering
• High-speed CMOS technology compatible with low-power TTL loads
• Wide operating temperature range suitable for industrial environments

Multivibrators Applications

• Timing pulse generation
• Frequency division
• Pulse width modulation
• Timer applications

Multivibrators Procurement Notes

Verify the specific ordering suffix G4 confirms RoHS compliance and green manufacturing status as per Texas Instruments standards. Ensure the TSSOP-16 package matches the target PCB footprint dimensions. Confirm that the logic family HC aligns with system voltage requirements before finalizing procurement orders.

Multivibrators Selection Notes

Select this component when dual independent timing channels are required in a compact surface-mount package. The HC series offers speed comparable to low-power Schottky TTL while maintaining CMOS low power characteristics. Verify input trigger compatibility and output load requirements against the specified 5.2 mA drive capability.

Multivibrators Part Context

This part belongs to the CD74HC4538 series of monostable multivibrators. It is functionally equivalent to other variants like CD74HC4538M but utilizes a TSSOP-16 package instead of SOIC. The device is designed for applications requiring precise timing pulses generated by external resistor and capacitor networks.

Multivibrators Replacement Considerations

CD74HC4538PWR is a direct pin-compatible alternative without the G4 suffix. CD74HC4538MG4 serves as a replacement if an SOIC-16 package is acceptable.
