Analog Devices Inc./Maxim Integrated MAX6817EUT-T

The MAX6817 accepts two mechanical switch inputs and suppresses contact bounce on both opening and closing. Each debounced output changes only after its input remains stable through the internal qualification interval. Integrated input pullups, an oscillator and undervoltage-lockout circuitry reduce the need for separate debounce components.

LCDChip registers the exact model as SOT-23-6, matching the manufacturer's MAX6817EUT-T ordering table and six-pin top-view drawing. Use the controlled package drawing for land pattern, pin-one orientation and assembly dimensions. The -T order code denotes the leaded ordering variant; do not infer that it is the later +T lead-free order code.

Layout checks

• Verify six-pin SOT-23 land pattern and pin-one orientation.
• Route each switch input separately from its CMOS output.
• Place supply bypassing near VCC and GND.

The registered JPG is missing locally and returns HTTP 404 on the production site. Restore and inspect it before publication.

The manufacturer's six-pin MAX6817 table identifies IN2 on pin 1, GND on pin 2, IN1 on pin 3, OUT2 on pin 4, VCC on pin 5 and OUT1 on pin 6.

Confirm the top-view pin-one marker on the physical package before board assembly.

Values and conditions follow the manufacturer's MAX6816/MAX6817/MAX6818 data sheet, Rev. 8. Absolute-maximum ratings are not normal operating conditions.

The single-channel MAX6816 and octal MAX6818 differ in channel count and package, so they are not pin-compatible substitutions. Other MAX6817 order codes may differ in temperature grade, lead finish or shipping format. Confirm the full order code, SOT-23-6 pinout, supply range, input protection and debounce timing before approving a replacement. No unverified LCDChip alternative is linked.

Maxim Integrated, now part of Analog Devices, documents this device in the MAX6816/MAX6817/MAX6818 CMOS switch-debouncer data sheet, Rev. 8. Its ordering table expressly identifies MAX6817EUT-T as a six-pin SOT-23-6, E-temperature order code.

Confirm manufacturer traceability, the six-pin package, top marking and pin-one orientation against controlled records. Verify input/output mapping and switch-opening and switch-closing delays in the actual circuit. Review lead finish for the exact -T order code.

Check the switch polarity and debounce-response budget in the host system. Input fault tolerance does not extend the VCC operating range. Restore and visually inspect the production SOT-23-6 JPG, then complete page and commercial-field checks before formal publication.
