NJM2374AM-TE1-#ZZZB from JRC, in a SOIC-8-208mil. 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 | CS | output | Collector of the internal output power transistor, tied to CD for the Darlington connection in the Vsat1 test condition (CS=CD). |
| 2 | ES | passive | Emitter of the internal output power transistor, tested with ES=GND; the switch rating is 1.5 A maximum. |
| 3 | CT | passive | Oscillator timing capacitor pin; oscillator frequency and switch ON/OFF time are specified against CT, with CT=1nF used for operating current tests. |
| 4 | GND | power_in | Ground reference pin for the device. |
| 5 | IN+ | input | Non-inverting error amplifier input compared against the 1.25 V (±2%) threshold Vth, with input bias current specified at 400 nA maximum. |
| 6 | V+ | power_in | Supply input rated 2.5 V (minimum 3.0 V at low temperature) to 40 V maximum; the NJM2374AE variant is rated to 48 V. |
| 7 | SI | input | Logic input that the datasheet only shows in test conditions (SI=V+); its function is not described in the text. |
| 8 | CD | output | Driver output for the internal power transistor; the Vsat2 test specifies Ic(driver) of 50 mA with forced beta of about 14. |
