TS3V555 - STMicroelectronics

TS3V555 3V LOW POWER SINGLE TIMERS

The TS3V555 with its low consumption (90µA at VCC = 3V) is a single CMOS timer dedicated to 3.3V or battery supply (specified at 3V and 5V) offering also a high frequency (f(max) 2MHz at VCC = 3V and 2.7 MHz at VCC = 5V). Thus, either in monostable or astable mode, timing remains very accurate. Timing capacitors can also be minimized due to high input impeda.
