Rainbow Electronics MAX16054 - Manual

General Description
The MAX16054 is a pushbutton on/off controller with a
single switch debouncer and built-in latch. It accepts a
noisy input from a mechanical switch and produces a
clean latched digital output after a factory-fixed qualifi-
cation delay.
The MAX16054 eliminates contact bounce during switch
opening and closing. The state of the output changes
only when triggered by the falling edge of the
debounced switch input; the output remains unchanged
on the rising edge of the input. Robust switch inputs
handle ±25V levels and are ±15kV ESD protected for
use in harsh industrial environments. The MAX16054
features a complementary output, OUT, which is the
inverted state of OUT. An asynchronous CLEAR input
allows an external signal to force the output flip-flop low.
Undervoltage-lockout circuitry ensures that OUT is in the
off state upon power-up. The MAX16054 requires no
external components, and its low supply current makes
it ideal for use in portable equipment.
The MAX16054 operates from a +2.7V to +5.5V single
supply. The MAX16054 is offered in a 6-pin thin SOT23
package and operates over the -40°C to +125°C auto-
motive temperature range.
