HCPL-3700-000E from Broadcom AVAGO, 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 | AC | input | AC sense input (with pin 4) for the threshold buffer; AC VTH+ is 4.9 V typ and VTH- is 3.7 V typ, and the input clamps to about 6.7 V typ when pins 2 and 3 are open. |
| 2 | DC+ | input | Positive DC sense input (with pin 3); DC VTH+ is 3.7 V typ and VTH- is 2.6 V typ, and the input current is 2.5 mA typ at threshold for HCPL-3700 (1.2 mA for HCPL-3760). |
| 3 | DC- | input | Negative DC sense input (with pin 2) and the reference for the DC input clamp, with the input current limited to a 50 mA average maximum per lead. |
| 4 | AC | input | AC sense input (with pin 1) for the threshold buffer; it is the second terminal for the AC threshold and clamp measurements in the datasheet. |
| 5 | GND | power_in | Ground reference for VCC and the open-collector output (pins 8-5 supply and pins 6-5 output), with VCC and VO each rated -0.5 V to 20 V relative to this pin. |
| 6 | VO | output | Open-collector logic output that is low (VOL 0.4 V max at IOL 4.2 mA, VCC 4.5 V) when the input exceeds VTH+ and high through an external pull-up when the input falls below VTH-; the average output current is limited to 30 mA and VO is rated -0.5 V to 20 V. |
| 7 | NC | unconnected | No internal connection; shown as NC on the schematic. |
| 8 | VCC | power_in | Supply pin with a recommended range of 2 V to 18 V and an absolute maximum of 20 V; a 0.01 µF ceramic bypass to pin 5 is recommended, and a series resistor RCC is advised where dVCM/dt may be very large. |
