SN74LVC1404DCUR from Texas Instruments, in a VSSOP-8. 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 | CTRL | input | OSC control input that disables the oscillator circuit when held low. |
| 2 | XOUT | output | Crystal connection output pin for external oscillator feedback. |
| 3 | XIN | input | Crystal connection input pin accepting signals from external resonator. |
| 4 | GND | power_in | Ground reference. |
| 5 | Y | output | Schmitt trigger inverter output providing buffered oscillator signal inverted from A input. |
| 6 | A | input | Schmitt trigger inverter input with hysteresis for signal conditioning. |
| 7 | OSCOUT | output | Unbuffered inverter output from the oscillator circuit. |
| 8 | VCC | power_in | Power supply voltage input with recommended operating range 1.65 V to 5.5 V. |
