STMICROELECTRONICS TS556IDTTR Dual CMOS Timer

The TS556 is a low-power dual CMOS timer designed for applications requiring minimal current consumption. It offers high frequency operation up to 2.7 MHz, very low supply current of 220 pA at 5V, and wide voltage range from 2V to 16V. Its pin-to-pin compatibility with bipolar NE556 makes it suitable for monostable and astable modes, providing accurate timing and reduced current spikes during output transitions. Its high input impedance and compatibility with TTL, CMOS, and logic MOS make it ideal for precision timing in various electronics and automation systems.
