Description and Introduction

Low Power Timer The TLC555QDR is a CMOS timer IC manufactured by Texas Instruments (TI). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:  

### **Specifications:**  
- **Supply Voltage Range:** 2 V to 15 V  
- **Low Power Consumption:** 170 µA (typical) at 5 V  
- **Operating Temperature Range:** -40°C to 125°C  
- **Output Current (Sink/Source):** 10 mA (minimum)  
- **Timing Accuracy:** ±1% (typical)  
- **Package Type:** SOIC-8  

### **Descriptions:**  
- The TLC555QDR is a CMOS version of the classic 555 timer, offering improved performance with lower power consumption and higher input impedance.  
- It is designed for precision timing, pulse generation, and oscillator applications.  
- Suitable for battery-powered and low-voltage applications due to its wide operating voltage range.  

### **Features:**  
- **Low Power:** Consumes significantly less power than bipolar 555 timers.  
- **Wide Supply Range:** Operates from 2 V to 15 V.  
- **High Input Impedance:** Reduces loading effects on timing components.  
- **Compatible with Bipolar 555:** Pin-compatible with standard 555 timers.  
- **Improved Timing Stability:** Lower susceptibility to supply voltage variations.  

This information is strictly based on the manufacturer's datasheet.

Application Scenarios & Design Considerations

Low Power Timer

Alternative Part Number

  • NE555DR --: Industry-standard 555 timer in the same SOIC-8 package with comparable supply range and output drive; widely available and pin-compatible for most timer applications.
  • ICM7555CBAZ --: CMOS 555 timer offering lower power consumption and higher input impedance than the bipolar TLC555, in an SOIC-8 footprint suitable as a functional substitute.
  • LMC555CMX --: CMOS 555 timer with very low supply current and rail-to-rail output, matching the low-power CMOS nature of the TLC555 in an SOIC-8 package.
