MAX913CSA+T

Maxim Integrated · Comparators · SO-8

MAX913CSA+T from Maxim Integrated, in a SO-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 V+ power_in Positive power supply, +5V; bypass to GND with a 0.1µF capacitor, and it also powers the digital output circuits.
2 IN+ input Noninverting comparator input; the common-mode input range is -5.2V to +3.5V with ±5V supplies and -0.2V to +3.5V with a single +5V supply.
3 IN- input Inverting comparator input, with the same common-mode input range as IN+ (-5.2V to +3.5V with ±5V supplies, -0.2V to +3.5V with a single +5V supply).
4 V- power_in Negative power supply, -5V for dual supplies (bypass to GND with a 0.1µF capacitor), or connect to GND for single-supply operation.
5 LE input Latch enable: Q and Q̄ are latched when LE is TTL high or floating, and the comparator is transparent when LE is low.
6 GND power_in Logic ground.
7 Q output TTL output of the comparator.
8 Q̄ output Complementary TTL output of the comparator.
