SN74AUC1G240DCKR from Texas Instruments, in a SC-70-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OE | input | Output-enable input; when OE is high the Y output is placed in the high-impedance (3-state) condition, and when OE is low Y follows A; tie OE to VCC through a pullup resistor to ensure the high-impedance state during power up or power down. |
| 2 | A | input | Data input to the buffer/driver; its logic level is passed to output Y when OE is low. |
| 3 | GND | power_in | Ground reference for the device. |
| 4 | Y | tri_state | 3-state buffer/driver output; reflects the logic level of A when OE is low (±8-mA drive at 1.8 V), and is placed in high-impedance state when OE is high. |
| 5 | VCC | power_in | Supply voltage input; device is operable from 0.8 V to 2.7 V but is designed specifically for 1.65-V to 1.95-V VCC operation. |
