DESCRIPTION
The TS3V556 with its low consumption (90µA/tim
at V_CC = 3V) is a dual CMOS timer dedicated to
3.3V or battery supply(specified at 3V and 5V offer-
ing also a high frequency (f_(max) 2MHz at V_CC = 3V
and 2.7 MHz at V_CC = 5V). Thus, either in mono-
stable or astable mode, timing remains very accu-
rate.
Timing capacitors can also be minimized due to
high input impedance (10¹² Ω).
