Maxim MAX16054AZT+T, MAX16054 Datasheet

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 qualifi­cation 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 auto­motive temperature range.

ABSOLUTE MAXIMUM RATINGS

ELECTRICAL CHARACTERISTICS

(VCC= +2.7V to +5.5V, TA= TJ= -40°C to +125°C, unless otherwise noted. Typical values are at VCC= +5V, TA= +25°C.) (Note 2)

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

Note 1: As per JEDEC 51 standard, multilayer board (PCB).
