DESCRIPTION
The TS3V556 with its low consumption (90µA/tim
at VCC= 3V) is a dual CMOS timer dedicated to
3.3Vor batterysupply(specified at 3Vand5Voffering also a highfrequency (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 (1012Ω).
