Product details

Dual-channel high-speed optocoupler for isolated signal paths

The HCPL0534 from onsemi packs two independent transistor-output optocouplers into a single 8-SOIC package, each channel rated for 2500Vrms isolation. Typical turn-on time is 450 ns and turn-off is 300 ns, fast enough for 1 MHz-ish isolated data links or gate-drive feedback paths without a dedicated high-speed digital isolator. The 15% minimum current transfer ratio at 16 mA forward current means the output transistor needs a pull-up resistor sized for that worst-case gain — plan for it in the logic-level translation stage.

Industrial temperature range and surface-mount package

Housed in an 8-SOIC wide-body (0.154-inch, 3.90 mm width) surface-mount package — the same footprint as many standard SOIC-8 optocouplers, so the PCB layout is straightforward to swap if needed. The 20V maximum output voltage and 8 mA per-channel output current suit 5V and 3.3V logic families directly, with a pull-up resistor to the rail.

Frequently asked questions

How do I get current pricing and availability for HCPL0534?

Submit an RFQ with your target quantity and preferred packaging (tube or tape-and-reel). We confirm pricing and lead time from our multi-supplier network at quote time — no automated stock counter, no stale numbers.

What is the difference between HCPL0534 and HCPL0530?

The HCPL0534 is a dual-channel optocoupler with a transistor output, while the HCPL0530 is a single-channel device with a transistor-with-base output. The base-access pin on the HCPL0530 allows external bias or speed-up networks; the HCPL0534 omits that pin for a simpler two-channel layout in the same 8-SOIC footprint.

Is HCPL0534 compatible with 5V logic?

Yes. The output transistor can sink up to 8 mA and the maximum output voltage is 20V, so with a pull-up resistor to 5V the output swings rail-to-rail and drives standard 5V CMOS or TTL inputs directly.

What is the closest functional second-source for HCPL0534?

The HCPL0534R2 is electrically identical — same dual-channel transistor output, same 2500Vrms isolation, same switching speeds — but packaged in tape-and-reel instead of tube. For a single-channel alternative, the HCPL0500R2 offers the same isolation and speed in a 1-channel transistor-with-base output.
