DESCRIPTION

The TS3V556 with its low consumption (90µA/tim

at VCC = 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 VCC = 3V

and 2.7 MHz at VCC = 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).
