COS4426SR 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; this pin is not connected in the SOP-8 package. |
| 2 | IN A | input | Input A is a high-impedance, TTL/CMOS compatible input with 300 mV hysteresis between its high and low thresholds, and it withstands negative inputs up to 5V. |
| 3 | GND | power_in | Device return pin that should have a low-impedance connection to the bias supply return, since high peak current flows out of this pin when the capacitive load is discharged. |
| 4 | IN B | input | Input B is a high-impedance, TTL/CMOS compatible input with 300 mV hysteresis between its high and low thresholds, and it withstands negative inputs up to 5V. |
| 5 | OUT B | output | Channel B low-impedance CMOS push-pull output; on the COS4426 it is out of phase with input B. |
| 6 | VDD | power_in | Bias supply for the driver, rated 4.5V to 25V with respect to the GND pin, and should be bypassed with local ceramic capacitors (1.0 µF suggested). |
| 7 | OUT A | output | Channel A low-impedance CMOS push-pull output; on the COS4426 it is out of phase with input A. |
| 8 | NC | unconnected | No connection; this pin is not connected in the SOP-8 package. |
