The NEC uPC4741 is a high‑performance quad operational amplifier with internal frequency compensation, low noise, and output short‑circuit protection. It is suited for AC signal‑amplifier applications such as active filters and pulse amplifiers.
The datasheet lists absolute maximum ratings, typical electrical characteristics, and recommended soldering processes for both surface‑mount (DIP and SOP) and through‑hole packages. Ordering information includes part numbers for the 14‑pin plastic DIP (HPCA741C) and SOP (BPCAT41G2) versions.

The device can be powered with a supply voltage from –0.3 V up to +40 V.
Peak package surface temperature should be 230 °C or below, with a reflow time of 30 seconds or less (210 °C or higher).
The uPC4741 can withstand an output short‑circuit for up to 10 seconds.
It is available in a 14‑pin plastic DIP (300 mil) and a 14‑pin plastic SOP (225 mil) package.
