Description and Introduction

Dual LinCMOS(TM) Timer The TLC556CDR is a dual timer integrated circuit (IC) manufactured by Texas Instruments. Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**
- **Manufacturer:** Texas Instruments (TI)  
- **Part Number:** TLC556CDR  
- **Type:** Dual Timer IC  
- **Technology:** CMOS  
- **Supply Voltage Range:** 2V to 15V  
- **Operating Temperature Range:** -40°C to 85°C  
- **Package:** SOIC-14  
- **Number of Timers:** 2 (Dual 555 Timer)  
- **Output Current:** 10mA (sink/source)  
- **Power Consumption:** Low power (CMOS technology)  
- **Timing Mode:** Astable (oscillator) and Monostable (one-shot)  
- **Trigger/Reset Voltage Levels:** CMOS-compatible  

### **Descriptions:**
The TLC556CDR is a dual version of the 555 timer, integrating two independent 555 timers in a single CMOS chip. It is designed for precision timing, pulse generation, and sequential timing applications. The CMOS technology ensures low power consumption while maintaining compatibility with TTL logic levels.  

### **Features:**
- **Low Power Consumption:** Due to CMOS technology.  
- **Wide Operating Voltage Range (2V to 15V):** Suitable for battery-powered applications.  
- **High Output Drive Capability:** Can directly drive TTL loads.  
- **Independent Timing Control:** Each timer operates independently.  
- **Improved Performance Over Bipolar 556:** Lower supply current and higher input impedance.  
- **ESD Protection:** Enhanced electrostatic discharge protection.  
- **Pin-Compatible with Bipolar 556:** Allows drop-in replacement in existing designs.  

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

Application Scenarios & Design Considerations

Dual LinCMOS(TM) Timer

Alternative Part Number

  • NE556DR --: Dual 555 timer in the same SOIC-8 package with equivalent function and widely available as a direct substitute.
  • LM556CMX --: Dual timer IC with similar electrical characteristics and pinout, suitable for most TLC556CDR applications.
  • ICM7556IPD --: Low-power CMOS dual 555 timer offering comparable performance and compatibility in the same package footprint.
  • NA556DR --: Dual 556 timer in SOIC-8 with the same pinout and timing function; a practical drop-in alternative when the tighter CMOS specifications of the TLC556 are not critical.
