DESCRIPTION
The TS3V555 with its low consumption (90µAat
V
CC
=3V) isasingleCMOStimerdedicatedto3.3V
or battery supply (specifiedat 3V and 5V) offering
also a highfrequency(f
(max)
2MHzatVCC=3Vand
2.7 MHz at V
CC
= 5V). Thus, either in monostable
or astablemode, timingremainsvery accurate.
Timing capacitors can also be minimized due to
high input impedance(10
12
Ω).
