TS556ID [STMicroelectronics]

The TS556 is a dual CMOS timer offering very low power consumption (220 µA typ at 5 V, 180 µA typ at 3 V) and high maximum astable frequency (2.7 MHz). It is pin-to-pin and functionally compatible with bipolar NE556(a), operates over a wide voltage range (2 V to 16 V), and features reduced supply current spikes during output transitions. With high input impedance (1012 W), timing capacitors can be minimized. It supports both monostable and astable modes with accurate timing.
