Description and Introduction

General Purpose timers The ICM7555 MTV is a timer IC manufactured by HAR (Harris Semiconductor).  

### **Specifications:**  
- **Supply Voltage Range:** 2V to 18V  
- **Low Power Consumption:** Typically 60µA at 5V  
- **Operating Temperature Range:** -55°C to +125°C  
- **Timing Accuracy:** ±2% over temperature  
- **Output Current:** Up to 100mA (sink or source)  
- **CMOS Technology:** Low power and high noise immunity  
- **Package Options:** Available in DIP, SOIC, and other surface-mount packages  

### **Description:**  
The ICM7555 MTV is a CMOS version of the classic 555 timer IC, offering improved performance with lower power consumption and higher input impedance. It is designed for precision timing, pulse generation, and oscillator applications.  

### **Features:**  
- **Low Power:** Consumes significantly less power than bipolar 555 timers  
- **Wide Voltage Range:** Operates from 2V to 18V  
- **High Output Drive Capability:** Can drive TTL loads  
- **Improved Timing Stability:** Less affected by supply voltage variations  
- **Pin-Compatible:** Direct replacement for standard 555 timers in most applications  
- **Low Trigger and Threshold Currents:** Reduces external component requirements  

This IC is commonly used in applications such as timers, oscillators, pulse generators, and delay circuits.

Application Scenarios & Design Considerations

General Purpose timers

Alternative Part Number

  • TLC555CP --: Low-power CMOS 555 timer, direct functional equivalent to the ICM7555 with similar supply range and pinout.
  • LMC555CN --: CMOS 555 timer offering low power consumption and wide supply voltage, a well-known drop-in replacement for ICM7555.
  • NE555P --: Classic bipolar 555 timer, pin-compatible and widely available, though with higher power consumption than the CMOS ICM7555.
