Description and Introduction

DUAL RETRIGGERABLE MONOSTABLE MULTIVIBRATOR The TC74HC4538AFN is a dual retriggerable monostable multivibrator manufactured by Toshiba. Below are its specifications, descriptions, and features:

### **Specifications:**  
- **Supply Voltage Range (VCC):** 2V to 6V  
- **High-Level Input Voltage (VIH):** 3.15V (min) at VCC = 4.5V  
- **Low-Level Input Voltage (VIL):** 1.35V (max) at VCC = 4.5V  
- **Output Current (IO):** ±5.2mA (max) at VCC = 4.5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-pin plastic SOP (Small Outline Package)  

### **Descriptions:**  
- The TC74HC4538AFN is a high-speed CMOS dual monostable multivibrator with retriggerable and reset capabilities.  
- It features independent trigger and reset inputs for each monostable circuit.  
- The output pulse width is determined by external timing components (resistor and capacitor).  
- Suitable for applications requiring precise timing control, such as pulse generation and delay circuits.  

### **Features:**  
- **Dual Monostable Multivibrator:** Contains two independent monostable circuits in a single package.  
- **Retriggerable Operation:** Allows the output pulse to be extended by reapplying the trigger input.  
- **Reset Function:** Immediate termination of the output pulse via the reset input.  
- **Wide Operating Voltage Range:** 2V to 6V, compatible with TTL and CMOS logic levels.  
- **Low Power Consumption:** Optimized for battery-operated devices.  
- **High Noise Immunity:** Ensures stable operation in noisy environments.  

This information is based on Toshiba's official datasheet for the TC74HC4538AFN.

Application Scenarios & Design Considerations

DUAL RETRIGGERABLE MONOSTABLE MULTIVIBRATOR

Alternative Part Number

  • SN74HC4538N --: Same dual retriggerable monostable multivibrator function in the HC logic family with matching pinout and 5V operation, widely available from a major logic supplier.
  • MC74HC4538AN --: Direct functional equivalent dual precision monostable multivibrator in HC logic, same DIP-16 footprint and timing behavior.
  • CD74HC4538E --: Pin-compatible dual retriggerable monostable multivibrator with equivalent HC logic characteristics, suitable drop-in replacement in most designs.
