Nexperia · Buffers, Drivers, Receivers, Transceivers · TSSOP-20

74AHC541PW from Nexperia, in a TSSOP-20. 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 OE0 input Active-LOW output enable input; a HIGH on OE0 causes the associated outputs to assume a high-impedance OFF-state.
2 A0 input Data input; inputs are overvoltage tolerant to 5.5 V and have Schmitt-trigger action.
3 A1 input Data input; inputs are overvoltage tolerant to 5.5 V and have Schmitt-trigger action.
4 A2 input Data input; inputs are overvoltage tolerant to 5.5 V and have Schmitt-trigger action.
5 A3 input Data input; inputs are overvoltage tolerant to 5.5 V and have Schmitt-trigger action.
6 A4 input Data input; inputs are overvoltage tolerant to 5.5 V and have Schmitt-trigger action.
7 A5 input Data input; inputs are overvoltage tolerant to 5.5 V and have Schmitt-trigger action.
8 A6 input Data input; inputs are overvoltage tolerant to 5.5 V and have Schmitt-trigger action.
9 A7 input Data input; inputs are overvoltage tolerant to 5.5 V and have Schmitt-trigger action.
10 GND power_in Ground (0 V) reference for all voltages on the device.
11 Y7 tri_state Data output; goes high-impedance (OFF-state) when the output enable conditions in the functional table are not met.
12 Y6 tri_state Data output; goes high-impedance (OFF-state) when the output enable conditions in the functional table are not met.
13 Y5 tri_state Data output; goes high-impedance (OFF-state) when the output enable conditions in the functional table are not met.
14 Y4 tri_state Data output; goes high-impedance (OFF-state) when the output enable conditions in the functional table are not met.
15 Y3 tri_state Data output; goes high-impedance (OFF-state) when the output enable conditions in the functional table are not met.
16 Y2 tri_state Data output; goes high-impedance (OFF-state) when the output enable conditions in the functional table are not met.
17 Y1 tri_state Data output; goes high-impedance (OFF-state) when the output enable conditions in the functional table are not met.
18 Y0 tri_state Data output; goes high-impedance (OFF-state) when the output enable conditions in the functional table are not met.
19 OE1 input Active-LOW output enable input; a HIGH on OE1 causes the associated outputs to assume a high-impedance OFF-state.
20 VCC power_in Supply voltage: 2.0 V to 5.5 V recommended for 74AHC541, and 4.5 V to 5.5 V for 74AHCT541.
