HCF4047M013TR

Multivibrators Overview

The HCF4047M013TR is a low-power monostable/astable multivibrator integrated circuit fabricated in Metal Oxide Semiconductor technology. It operates within a supply voltage range of 3V to 20V and supports an operating temperature range of -55°C to +125°C. The device features buffered true and complemented outputs (Q, Q) and an oscillator output. It requires only one external resistor and capacitor for timing configuration. Quiescent current is specified up to 20V, with maximum input leakage current at 100nA at VDD = 18V and TA = 25°C.

Multivibrators Feature Summary

• Supports both monostable (one-shot) and astable (free-running) operation modes using a single external resistor and capacitor.
• Provides true and complemented buffered outputs along with a dedicated oscillator output terminal.
• Capable of positive or negative edge-triggered monostable action with retriggering functionality.
• Includes buffered inputs and an external reset option for reliable system control.

Multivibrators FAQ

What are the required external components for operation?

Only one external resistor and one external non-polarized capacitor are required to set the timing parameters for both astable and monostable modes.

How is the monostable mode triggered?

Monostable mode can be triggered by a positive-edge pulse on the +TRIGGER input or a negative-edge pulse on the -TRIGGER input, depending on the state of the other trigger input.
