Tact switch controller
|
AS2M1 –
Tact switch (toggle) controller, SPDT analog switch |
ThThe AS2M1 is a tact switch controller with anti-bounce block, which
“converts” tact switch into toggle switch and controls SPDT
analog
switch with (LED) indication on digital output status of toggle switch.
During Power-On NС input is connected to COM and OUT is switched to
+Vсс. If “high-current”-signal is applied to SW, after
anti-bounce
delay (approximately 80 ms) , internal trigger change it’s status and
switching SPDT switch and Out.
Inputs SW and R are current inputs. If
current flowing out from SW or R is less than 100 uA, then input level
is high.
If external circuit sources from those inputs more than 100
mA, then input level is low.
Transition from high level to low level leads to change of status of
internal trigger (after anti-bounce delay).
Low level on Reset input
resets internal trigger to initial state. During low level on Reset
input controller don’t response on SW input. |
