TS3V555I
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
. PIN-TO-PIN AND FUNCTIONALLY COMPAT-
. IBLE WITH BIPOLAR NE555 AND CMOS
TS555
OUTPUT COMPATIBLE WITH TTL,CMOS
AND LOGIC MOS
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 ).
