AIP74HC541SA20.TR from Wuxi I core Elec, in a SOP-20-300mil. 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 | OE1 | input | Active-LOW output enable input; a HIGH level on OE1 forces the Y outputs into the high-impedance OFF-state. |
| 2 | A0 | input | Data input for channel 0; the inputs have clamp diodes so current-limiting resistors can interface them to voltages above VCC, with CMOS levels for AiP74HC541 and TTL levels for AiP74HCT541. |
| 3 | A1 | input | Data input for channel 1; the inputs have clamp diodes so current-limiting resistors can interface them to voltages above VCC, with CMOS levels for AiP74HC541 and TTL levels for AiP74HCT541. |
| 4 | A2 | input | Data input for channel 2; the inputs have clamp diodes so current-limiting resistors can interface them to voltages above VCC, with CMOS levels for AiP74HC541 and TTL levels for AiP74HCT541. |
