RESET

(IMP811)

140ms minimum after the reset conditions are removed. In addition, RESET is active LOW

as long as the manual reset is low.

RESET

(IMP812)

140ms minimum after the reset conditions are removed. In addition, RESET is active

HIGH as long as the manual reset is low.

3

MR

Manual Reset Input. A logic LOW on MR asserts RESET. RESET remains active as long

as MR is LOW and for 180ms after MR returns HIGH. The active low input has an internal

20k

Ω pull-up resistor. The input should be left open if not used. It can be driven by TTL or

CMOS logic or shorted to ground by a switch..
