SN65EPT21DGKR from Texas Instruments, in a VSSOP-8-0.65mm. 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 | NC | unconnected | No connect. Leave floating. |
| 2 | D | input | Non-inverting differential LVPECL/LVDS/CML input. Internal 50 kΩ pull-down; add external pull-up per pin-assignment note. Bias to VBB when used single-ended. |
| 3 | D_N | input | Inverting differential LVPECL/LVDS/CML input (D-bar). Internal 50 kΩ pull-up; add external pull-up per pin-assignment note. Bias to VBB when used single-ended. |
| 4 | VBB | output | Output reference voltage (~VCC/2, typ 2.03 V at VCC=3.3 V). Used to bias unused input in single-ended mode; place a 0.01 µF decoupling capacitor between VCC and VBB when used. Limit sink/source current to < 0.5 mA. Leave open when not used. |
| 5 | GND | power_in | Ground (0 V) reference for the device. |
| 6 | NC | unconnected | No connect. Leave floating. |
| 7 | Q | output | LVTTL/LVCMOS single-ended output, 24 mA drive. VOH ≥ 2.4 V at IOH = -3 mA; VOL ≤ 0.5 V at IOL = 24 mA. |
| 8 | VCC | power_in | Positive supply, 3.0 V to 3.6 V (nominal 3.3 V). Absolute maximum 3.8 V. |
