DESCRIPTION
The TS3V555 with its low consumption (90µA at
V_CC = 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 V_CC = 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).
