Description
The TLC555CDR is a low-power CMOS version of the classic 555 timer IC, designed by Texas Instruments. It offers improved performance with lower power consumption, wider voltage range (2V to 15V), and reduced supply current compared to the original bipolar NE555.
Key features:
- Low power: ~80µA typical supply current.
- High precision timing: Stable operation in monostable (one-shot) or astable (oscillator) modes.
- Wide operating range: Suitable for battery-powered applications.
- Pin-compatible with standard 555 timers.
Common applications include pulse generation, LED flashers, tone generation, and delay circuits. The TLC555CDR comes in an SOIC-8 package, making it suitable for space-constrained designs.
Its CMOS construction reduces output current (~100mA sink/source) compared to the NE555, but it remains versatile for most low-to-medium power timing tasks.
For detailed specs, refer to the Texas Instruments datasheet.
