ISL4089IBZ-T7 from RENESAS, in a SOIC-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 | IN- | input | Video amplifier inverting input. |
| 2 | IN+ | input | Video amplifier non-inverting input. |
| 3 | VREF | power_in | Restore amplifier VREF input sets the programmable restored DC output level, and the datasheet states VREF can sense down to the negative supply. |
| 4 | HOLD | input | Hold/restore TTL/CMOS logic input where logic 0 selects the restore state and logic 1 selects the hold state; VIL max is 0.8V and VIH min is 2.0V. |
| 5 | GND | power_in | Ground reference for the single +5V supply and the signal pins. |
| 6 | NC | unconnected | No internal connection; it can be tied to the -5V pin in existing EL4089 applications. |
| 7 | VOUT | output | Video amplifier output, which must be limited to less than 60mA continuous because the part has no output short-circuit current limit. |
| 8 | V+ | power_in | Positive single supply; the absolute maximum voltage between V+ and GND is 5.5V, with +5V nominal operation. |
