Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OE0 | input | Output enable input (active LOW); when HIGH, drives all outputs Y0-Y7 to high-impedance state. |
| 2 | A0 | input | Data input for 8-bit buffer; TTL-level compatible with overvoltage tolerance. |
| 3 | A1 | input | Data input for 8-bit buffer; TTL-level compatible with overvoltage tolerance. |
| 4 | A2 | input | Data input for 8-bit buffer; TTL-level compatible with overvoltage tolerance. |
| 5 | A3 | input | Data input for 8-bit buffer; TTL-level compatible with overvoltage tolerance. |
| 6 | A4 | input | Data input for 8-bit buffer; TTL-level compatible with overvoltage tolerance. |
| 7 | A5 | input | Data input for 8-bit buffer; TTL-level compatible with overvoltage tolerance. |
| 8 | A6 | input | Data input for 8-bit buffer; TTL-level compatible with overvoltage tolerance. |
| 9 | A7 | input | Data input for 8-bit buffer; TTL-level compatible with overvoltage tolerance. |
| 10 | GND | power_in | Ground (0 V). |
| 11 | Y7 | tri_state | Data output with 3-state control; high-impedance when OE0 or OE1 is HIGH. |
| 12 | Y6 | tri_state | Data output with 3-state control; high-impedance when OE0 or OE1 is HIGH. |
| 13 | Y5 | tri_state | Data output with 3-state control; high-impedance when OE0 or OE1 is HIGH. |
| 14 | Y4 | tri_state | Data output with 3-state control; high-impedance when OE0 or OE1 is HIGH. |
| 15 | Y3 | tri_state | Data output with 3-state control; high-impedance when OE0 or OE1 is HIGH. |
| 16 | Y2 | tri_state | Data output with 3-state control; high-impedance when OE0 or OE1 is HIGH. |
| 17 | Y1 | tri_state | Data output with 3-state control; high-impedance when OE0 or OE1 is HIGH. |
| 18 | Y0 | tri_state | Data output with 3-state control; high-impedance when OE0 or OE1 is HIGH. |
| 19 | OE1 | input | Output enable input (active LOW); when HIGH, drives all outputs Y0-Y7 to high-impedance state. |
| 20 | VCC | power_in | Supply voltage; 4.5 V to 5.5 V for 74AHCT541. |
