COS4427DT from COSINE, in a DIP-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 internally connected on the COS4427. |
| 2 | IN A | input | MOSFET driver input A is high-impedance and TTL/CMOS compatible, with 300 mV of hysteresis between its high and low thresholds to prevent output glitching on slow edges. |
| 3 | GND | power_in | Ground is the device return pin and must have a low-impedance connection to the bias supply return, since high peak current flows out of it when the capacitive load discharges. |
| 4 | In B | input | MOSFET driver input B is high-impedance and TTL/CMOS compatible, with 300 mV of hysteresis between its high and low thresholds to prevent output glitching on slow edges. |
| 5 | OUT B | output | Channel B output is a low-impedance CMOS push-pull output whose pull-down and pull-up devices have equal strength, giving equal rise and fall times. |
| 6 | VDD | power_in | Bias supply for the MOSFET driver, rated 4.5V to 24V with respect to the GND pin, and should be bypassed with local ceramic capacitors (1.0 µF suggested). |
| 7 | OUT A | output | Channel A output is a low-impedance CMOS push-pull output whose pull-down and pull-up devices have equal strength, giving equal rise and fall times. |
| 8 | NC | unconnected | No connection; this pin is not internally connected on the COS4427. |
