TS556 is a dual CMOS timer that offers very low power consumption and high frequency. It provides accurate timing in both monostable and astable modes. The TS556 reduces supply current spikes during output transitions, allowing for the use of lower decoupling capacitors. Timing capacitors can also be minimized due to high input impedance.
The TS556 dual CMOS timer provides very low power consumption (220 µA typical at 5 V) and a wide supply voltage range of +2 V to +16 V. It is pin‑to‑pin compatible with the bipolar NE556 and offers high output current capability, making it suitable for applications that require low supply current spikes.
The device includes detailed static and dynamic electrical characteristics, package mechanical data for both DIP‑14 and SO‑14 formats, and application notes for monostable operation. Typical specifications such as a maximum astable frequency of 2.7 MHz and an input impedance of 10¹² Ω are provided.
