The PS9324L2-V-E3-AX: The PS9324L2-V--AX: The Renesas PS9324L2-V--AX is a single-channel optocoupler with an open-collector output, designed for industrial and power-conversion applications that require galvanic isolation. Its 5000Vrms isolation rating suits motor-drive I/O, PLC digital inputs, and isolated DC-DC feedback paths where the primary side and secondary side must be electrically separated.
10Mbps data rate — bus margin for industrial fieldbus
At 10Mbps, this part handles Profibus DP, DeviceNet, and most PLC backplane links without timing pressure. The 75 ns max propagation delay (both directions) and 20 ns rise / 5 ns fall times leave comfortable margin for a 100 ns bit period — no need to tighten the PCB trace length budget. If your application runs closer to 15Mbps or requires push-pull output, the RV1S9062 peer family is worth a look.
15kV/µs CMTI — why it matters for noisy environments
Common-mode transient immunity of 15kV/µs (minimum) means the output stays clean when a common-mode step slams across the isolation barrier — typical in IGBT gate-drive circuits and motor-drive inverter nodes.
Package and supply range
Housed in a 6-SOIC (0.268", 6.80 mm width) with a 6-SDIP gull-wing footprint, this is a surface-mount part that reflows on a standard lead-free profile. The input LED forward voltage is 1.55 V typical — a 330 Ω series resistor from a 3.3 V logic pin gives about 5 mA forward current, well within the 25 mA absolute max.
