This document describes the features and characteristics of the TS556 low-power dual CMOS timer, revised in October 2008. It includes very low power consumption, high maximum astable frequency, wide voltage range, reduced supply current spikes during output transitions, high input impedance, and pin-to-pin and functionally compatibility with the bipolar NE556.
The TS556 is a dual CMOS timer designed for very low power consumption and high maximum astable frequency. It offers pin-to-pin and functional compatibility with the bipolar NE556 while providing reduced supply current spikes during output transitions. The device supports a wide voltage range from 2 V to 16 V.
| Supply voltage range | 2 V to 16 V |
|---|---|
| Maximum astable frequency | 2.7 MHz |
| Supply current (typical at 5V) | 220 µA |
| Supply current (typical at 3V) | 180 µA |
| Output compatible with | TTL, CMOS and logic MOS |
The absolute maximum supply voltage is +18 V.
The maximum astable frequency is 2.7 MHz.
The typical supply current is 220 µA at +5 V.
