The published copy was built by 2.18.0, which imported every KiCad roundrect and oval pad as a SQUARE EAGLE smd; this carries the real pad shape across (0 -> 5 rounded pads) and stops dropping geometry drawn on KiCad User.N layers. Attributes, connects, pads and the pin-1 marker are gated against decreasing and are unchanged. · Ray 1mo ago

TS391AG-AF5-R

UTC Unisonic Tech · Comparators · SOT-25-5

TS391AG-AF5-R from UTC Unisonic Tech, in a SOT-25-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 IN(+) input Non-inverting comparator input. Input common-mode range includes ground and extends up to VCC-1.5V; may go to +30V without damage. Input bias current is typ. 25 nA (out of the pin due to PNP input stage).
2 GND power_in Device ground / negative supply reference. In single-supply operation, tie to 0V; in dual-supply operation, tie to the negative rail (down to -18V).
3 IN(-) input Inverting comparator input. Same common-mode constraints as IN(+); differential input voltage range equals the supply voltage (up to ±36V).
4 Output output Open-collector comparator output. Requires an external pull-up resistor to VCC (or another logic rail up to +36V). Low-level output voltage is typ. 250 mV at IOUT=4 mA; sink capability is typ. 16 mA. Compatible with TTL, DTL, ECL and CMOS.
5 VCC power_in Positive supply pin. Single-supply range +2V to +36V, or ±1V to ±18V split supply. Supply current is typ. 0.2 mA at VCC=5V and independent of supply voltage.
