HT6541BRTZ

HTCSEMI · Comparators · SOT-23-5

HT6541BRTZ from HTCSEMI, 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 VIN+ input Non-inverting comparator input with a rail-to-rail input range of VSS - 0.3V to VDD + 0.3V, and input current limited to ±2 mA.
2 VSS power_in Negative power supply, connected to ground in single-supply operation (VDD - VSS maximum 7.0V).
3 VIN- input Inverting comparator input with a rail-to-rail input range of VSS - 0.3V to VDD + 0.3V, and input current limited to ±2 mA.
4 OUT output Push-pull CMOS/TTL-compatible comparator output with rail-to-rail swing, with output current limited to ±30 mA absolute maximum.
5 VDD power_in Positive power supply for 1.6V to 5.5V operation, with a local 0.01 µF to 0.1 µF bypass capacitor recommended.

  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: ht6541brtz-etched.step / ht6541brtz-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ht6541brtz.step / ht6541brtz.glb are the bare package body.
