HJ421-2 is a dual-channel optocoupler circuit. Each channel consists of an input interface circuit with high anti-interference capability, a CaAsP light-emitting diode, and an NPN phototransistor. It features compatibility with signal input and TTL/CMOS circuits, an output transistor withstand voltage greater than 35V, an insulation resistance between input and output greater than 10¹⁰Ω, isolation voltage ≥1000V, and a high current transfer ratio. It uses an 8-wire flat ceramic package to reduce size; the input already includes series and parallel resistors, allowing direct interfacing with TTL/CMOS circuits without the need for external current-limiting resistors during use, simplifying design and increasing system assembly density; the output configuration is flexible and can be set up in a redundant manner to enhance reliability. The operating temperature range is -55~+125℃.
The packaging form uses F08-04A fully sealed packaging, and the dimensions are shown in Appendix 1, Figure 9.
