TLV1851QDBVRQ1

Texas Instruments · Comparators · SOT-23-5

TLV1851QDBVRQ1 from Texas Instruments, in a SOT-23-5. 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 OUT output Push-pull output of the TLV1851-Q1 comparator, which the absolute maximum ratings limit to -0.3 V to (V+) + 0.3 V referenced to (V-).
2 V- power_in Negative supply voltage; the supply is rated 1.8 V to 40 V between (V+) and (V-), with an absolute maximum supply voltage of 42 V.
3 IN+ input Non-inverting (+) comparator input with over-the-rail common-mode range extending 40 V above (V-), and input pins rated -0.3 V to 42 V from (V-) with ±10 mA maximum input current.
4 IN- input Inverting (-) comparator input with over-the-rail common-mode range extending 40 V above (V-), and input pins rated -0.3 V to 42 V from (V-) with ±10 mA maximum input current.
5 V+ power_in Positive supply voltage; the supply is rated 1.8 V to 40 V between (V+) and (V-), with an absolute maximum supply voltage of 42 V.
