Type: CMOS 555 Timer (low-power variant)
Package: SOIC-8
Supply Voltage: 2V to 15V (wide range)
Quiescent Current: 100µA (typical at 5V)
Output Sink/Source Current: 10mA (min), 100mA (max for CMOS version)
Operating Frequency: Up to 2.1MHz (vs. 100kHz for NE555)
Rise/Fall Time: 100ns (typical)
| Parameter | TLC555C (CMOS) | NE555 (Bipolar) |
|---|---|---|
| Supply Voltage | 2V–15V | 4.5V–16V |
| Quiescent Current | 100µA | 3–10mA |
| Max Frequency | 2.1MHz | 100kHz |
| Output Current | 10–100mA | 200mA |
Low Power: Ideal for battery-operated devices.
High Input Impedance: ≤10¹²Ω (CMOS inputs).
TTL-Compatible Output: Works with 3.3V/5V logic.
Improved Temperature Stability: Better than bipolar 555.
