MC34161DR2G

onsemi · Monitors & Reset Circuits · SOIC-8

MC34161DR2G from onsemi, in a SOIC-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 Vref power_out Pinned-out 2.54 V reference output (2.48 V to 2.60 V at 25°C), able to source more than 2.0 mA with short-circuit current limit protection.
2 Input 1 input Channel 1 comparator input with 1.27 V typical threshold and 25 mV typical hysteresis; input range is -1.0 V to +40 V.
3 Input 2 input Channel 2 comparator input with 1.27 V typical threshold and 25 mV typical hysteresis; input range is -1.0 V to +40 V.
4 GND power_in Ground reference for the device.
5 Output 2 output Channel 2 open-collector output that can sink more than 10 mA (20 mA maximum) and is rated to 40 V.
6 Output 1 output Channel 1 open-collector output that can sink more than 10 mA (20 mA maximum) and is rated to 40 V.
7 Mode Select input Tristate Mode Select input (GND, Vref or VCC) that sets Channels 1 and 2 as inverting or noninverting, with thresholds of about 0.63 V and Vref + 0.23 V.
8 VCC power_in Positive supply input, 2.0 V to 40 V for positive voltage sensing and 4.0 V to 40 V for negative voltage sensing.
