The Renesas ISL59446IRZ is a 4:1 multiplexer-amplifier that combines three independent video mux channels into a single 32-QFN package. Its 1600 V/µs slew rate and 620 MHz -3 dB bandwidth let it pass high-resolution video (1080p and beyond) with minimal slew-induced distortion, which is the usual failure mode when a generic op-amp tries to switch fast enough for a multi-input display or KVM switch.
Supply current and thermal design
At 44 mA supply current, the ISL59446IRZ sits in the moderate-power range for a three-channel video mux. The exposed pad is the primary heat path — the board layout should connect it to a ground plane with at least four vias.
Active lifecycle and RoHS compliance
The ROHS3 compliance covers the full substance restriction list, which simplifies compliance declarations for EU-market equipment.
