LM2903HYDT

STMicroelectronics · Comparators · SO-8

LM2903HYDT from STMicroelectronics, 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 Output 1 output Output 1 of dual comparator with low saturation voltage of 250 mV typ. at 4 mA sink current and TTL/CMOS compatibility.
2 Inverting input 1 input Inverting input of comparator 1 with input offset current 5 nA typ., input bias current 25 nA typ., and common-mode range 0 to (VCC+) - 1.5 V.
3 Non-inverting input 1 input Non-inverting input of comparator 1 with input offset current 5 nA typ., input bias current 25 nA typ., and common-mode range 0 to (VCC+) - 1.5 V.
4 VCC- power_in Negative supply voltage, ground in single supply mode or negative supply in dual supply mode.
5 Non-inverting input 2 input Non-inverting input of comparator 2 with input offset current 5 nA typ., input bias current 25 nA typ., and common-mode range 0 to (VCC+) - 1.5 V.
6 Inverting input 2 input Inverting input of comparator 2 with input offset current 5 nA typ., input bias current 25 nA typ., and common-mode range 0 to (VCC+) - 1.5 V.
7 Output 2 output Output 2 of dual comparator with low saturation voltage of 250 mV typ. at 4 mA sink current and TTL/CMOS compatibility.
8 VCC+ power_in Positive supply voltage with range 2 V to 36 V for single supply or ±1 V to ±18 V for dual supply.
