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. |
