COS4427SR from COSINE, in a SOP-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 | NC | unconnected | No connection. |
| 2 | IN A | input | Input A is a high-impedance TTL/CMOS compatible input with 300 mV of hysteresis between the high and low thresholds (VIH 1.8 V, VIL 0.7 V). |
| 3 | GND | power_in | Ground is the device return pin, and it should have a low-impedance connection to the bias supply source return; high peak current flows out of it when the capacitive load is discharged. |
| 4 | In B | input | Input B is a high-impedance TTL/CMOS compatible input with 300 mV of hysteresis between the high and low thresholds (VIH 1.8 V, VIL 0.7 V). |
| 5 | OUT B | output | Output B is a low-impedance CMOS push-pull output; for the COS4427 it is in phase with input B. |
| 6 | VDD | power_in | VDD is the bias supply for the driver, rated for 4.5 V to 25 V with respect to the Ground pin, and should be bypassed with local ceramic capacitors (1.0 µF suggested). |
| 7 | OUT A | output | Output A is a low-impedance CMOS push-pull output; for the COS4427 it is in phase with input A. |
| 8 | NC | unconnected | No connection. |
