PTC Princeton Tech · RF Transceiver ICs · SOT-23-6
PT4450 from PTC Princeton Tech, in a SOT-23-6. 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 | OSCOUT | output | Oscillator output of the SAW oscillator; the datasheet gives no further electrical limits for this pin. |
| 2 | VSS | power_in | Ground connection; all voltages are referenced to VSS = 0 V. |
| 3 | PAOUT | output | Power amplifier output, typically +10 dBm at 434 MHz, with the exact output power depending on the power amplifier output matching. |
| 4 | DIN | input | Data input that also enables the chip, with a data rate of 0.5 to 50 Kbps and a standby current of 1 µA maximum when DIN is low. |
| 5 | VDD | power_in | Power supply, recommended 2.2 V to 3.6 V (absolute maximum VSS-0.3 V to VSS+5.0 V). |
| 6 | OSCIN | input | Oscillator input to the SAW oscillator; the datasheet gives no further electrical limits for this pin. |
