HCNW4506#500

Logic Output Optoisolators Overview

The HCNW4506#500 is a logic output optoisolator featuring an AlGaAs LED and open collector, Schottky-clamped output. It provides 5000Vrms isolation with a minimum common-mode transient immunity of 15kV/µs. The device operates within a supply voltage range of 4.5V to 30V and supports a maximum DC forward current of 25mA. Output current per channel is rated at 15mA. Propagation delays are specified as 550ns (tpLH) and 400ns (tpHL). The typical forward voltage is 1.6V. It is housed in an 8-DIP gull-wing package and functions across a temperature range of -40°C to 100°C.

Logic Output Optoisolators Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status, as specific variants may differ from standard lead-free specifications. Ensure the ordering suffix matches the required package style. Request official datasheets and certification documents prior to finalizing procurement orders to guarantee technical suitability.

Logic Output Optoisolators Selection Notes

Select this component when high-speed digital isolation is required alongside robust noise immunity. The open collector output necessitates an external pull-up resistor for proper logic level generation. Verify that the required isolation voltage and CMTI ratings meet system safety standards. Consider thermal management requirements given the operating temperature range and power dissipation characteristics.

Logic Output Optoisolators Part Context
