TS3V555

TS3V555 3V LOW POWER SINGLE TIMERS . . . . . . . . DEDICATED TO 3.3V OR BATTERY SUPPLY (Specified at 3V and 5V) VERY LOW POWER CONSUMPTION : 90µA at VCC = 3V WIDE SINGLE SUPPLY RANGE : +2.7V to +16V HIGH OUTPUT CURRENT CAPABILITY SUPPLY CURRENT SPIKES REDUCED DURING OUTPUT TRANSITIONS HIGH INPUT IMPEDANCE : 1012 Ω PIN-TO-PIN AND FUNCTIONALLY COMPATIBLE WITH BIPOLAR NE555 AND CMOS TS555 OUTPUT COMPATIBLE WITH TTL,CMOS AND LOGIC MOS N DIP8 (Plastic Package) D SO8 (Plastic Micropackage) DESCRIPTION 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 impedance (1012 Ω).
