Description and Introduction

2.1-MHz, 250-?A, Low-Power Timer 8-SOIC 0 to 70 The TLC555CDG4 is a CMOS version of the 555 timer IC manufactured by Texas Instruments. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Supply Voltage Range:** 2V to 15V  
- **Low Power Consumption:** 0.8mA (typical at 5V)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Output Current (Sink/Source):** 10mA (minimum)  
- **Timing Accuracy:** ±1% (typical)  
- **Package Type:** SOIC-8  

### **Descriptions:**
- The TLC555CDG4 is a highly stable, low-power CMOS timer IC designed for precision timing applications.  
- It is a drop-in replacement for the NE555 but with improved performance, including lower power consumption and higher input impedance.  
- Suitable for monostable (one-shot) and astable (oscillator) applications.  

### **Features:**
- **CMOS Technology:** Ensures low power consumption and high noise immunity.  
- **Wide Supply Voltage Range:** Operates from 2V to 15V, making it versatile for various applications.  
- **High Output Drive Capability:** Can drive TTL loads directly.  
- **Low Trigger and Reset Current:** Enhances efficiency in battery-powered applications.  
- **Improved Timing Stability:** Less sensitive to supply voltage variations compared to bipolar versions.  

This IC is commonly used in timing circuits, pulse generation, LED flashers, and other precision timing applications.

Application Scenarios & Design Considerations

2.1-MHz, 250-?A, Low-Power Timer 8-SOIC 0 to 70

Alternative Part Number

  • NE555DR --: Industry-standard 555 timer in SOIC-8, pin-compatible with TLC555 and widely available; lower input impedance than the CMOS TLC555 but functionally interchangeable in most timer circuits.
  • ICM7555CBAZ --: CMOS 555 timer with low power consumption and high input impedance similar to the TLC555, suitable drop-in replacement in SOIC-8 timing applications.
  • LMC555CMX --: CMOS 555 timer offering very low supply current and rail-to-rail output, closely matching TLC555 characteristics for low-power timing designs.
