SN74HCT541DBR from Texas Instruments, in a SSOP-20-208mil. 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 1; if OE1 or OE2 is high, all eight outputs are in the high-impedance state. |
| 2 | A1 | input | Buffer data input 1, TTL-compatible with VIH min 2 V and VIL max 0.8 V. |
| 3 | A2 | input | Buffer data input 2, TTL-compatible with VIH min 2 V and VIL max 0.8 V. |
| 4 | A3 | input | Buffer data input 3, TTL-compatible with VIH min 2 V and VIL max 0.8 V. |
| 5 | A4 | input | Buffer data input 4, TTL-compatible with VIH min 2 V and VIL max 0.8 V. |
| 6 | A5 | input | Buffer data input 5, TTL-compatible with VIH min 2 V and VIL max 0.8 V. |
| 7 | A6 | input | Buffer data input 6, TTL-compatible with VIH min 2 V and VIL max 0.8 V. |
| 8 | A7 | input | Buffer data input 7, TTL-compatible with VIH min 2 V and VIL max 0.8 V. |
| 9 | A8 | input | Buffer data input 8, TTL-compatible with VIH min 2 V and VIL max 0.8 V. |
| 10 | GND | power_in | Ground reference for the device. |
| 11 | Y8 | tri_state | Three-state true-data output 8 with ±6 mA drive at 5 V, high-impedance when either OE is high. |
| 12 | Y7 | tri_state | Three-state true-data output 7 with ±6 mA drive at 5 V, high-impedance when either OE is high. |
| 13 | Y6 | tri_state | Three-state true-data output 6 with ±6 mA drive at 5 V, high-impedance when either OE is high. |
| 14 | Y5 | tri_state | Three-state true-data output 5 with ±6 mA drive at 5 V, high-impedance when either OE is high. |
| 15 | Y4 | tri_state | Three-state true-data output 4 with ±6 mA drive at 5 V, high-impedance when either OE is high. |
| 16 | Y3 | tri_state | Three-state true-data output 3 with ±6 mA drive at 5 V, high-impedance when either OE is high. |
| 17 | Y2 | tri_state | Three-state true-data output 2 with ±6 mA drive at 5 V, high-impedance when either OE is high. |
| 18 | Y1 | tri_state | Three-state true-data output 1 with ±6 mA drive at 5 V, high-impedance when either OE is high. |
| 19 | OE2 | input | Active-low output enable 2; if OE1 or OE2 is high, all eight outputs are in the high-impedance state. |
| 20 | VCC | power_in | Supply voltage, 4.5 V to 5.5 V recommended, with a 0.1-µF bypass capacitor placed close to the pin. |
