HCF4538M013TR

Multivibrators Overview

The HCF4538M013TR is a dual precision monostable multivibrator fabricated in Metal Oxide Semiconductor technology. It provides stable retriggerable and resettable one-shot operation for fixed voltage timing applications. The circuit utilizes an external resistor (RX) and capacitor (CX) to control timing, with pulse widths ranging from nanoseconds to seconds. Trigger propagation delays are independent of the external RC components. The device operates within a supply voltage range of 3V to 20V and features Schmitt trigger inputs allowing unlimited rise and fall times.

Multivibrators Feature Summary

• Retriggerable and resettable capability for flexible timing control
• Schmitt trigger inputs allow unlimited rise and fall times on trigger signals
• Separate reset inputs for immediate termination of output pulses
• Buffered Q and complementary outputs available

Multivibrators Applications

• Fixed voltage timing applications
• Pulse width generation
• Timing delay circuits
• Frequency division

Multivibrators Procurement Notes

Verify the package type matches the design requirements, as this part number corresponds to the SOP-16 tape and reel configuration. Confirm that the operating temperature range of -55°C to +125°C aligns with the system environment. Ensure external component values for RX and CX adhere to the specified minimum and maximum limits to maintain timing accuracy.

Multivibrators Selection Notes

Select this component when precise monostable timing is required with independent trigger and reset propagation delays. The Schmitt trigger inputs are suitable for noisy environments or signals with slow transition times. Consider the SOP-16 package if surface mount assembly is preferred over through-hole DIP options.

Multivibrators Part Context

This device belongs to the HCF4538B series of dual monostable multivibrators. It is manufactured using CMOS technology, offering high noise immunity and low power consumption. The series is designed to meet JEDEC standards for B-series CMOS devices, ensuring compatibility with standard logic families.

Multivibrators Replacement Considerations

Check for pin-compatible alternatives such as the HCF4538BEY in DIP packaging if surface mount is not required. Verify electrical specifications against other dual monostable multivibrators from different manufacturers to ensure functional equivalence.
