HCPL-7723-320E

Logic Output Optoisolators Overview

The HCPL-7723-320E is a high-speed CMOS optocoupler manufactured by Broadcom Limited. It features a single channel with a data rate of 50 Mb/s and an isolation voltage of 3750 Vrms. The device utilizes a push-pull, totem pole output type capable of sourcing or sinking 10 mA. Key timing parameters include a typical rise time of 8 ns, fall time of 6 ns, and maximum propagation delay of 22 ns for both low-to-high and high-to-low transitions. It operates within a temperature range of -40°C to +85°C and is housed in an 8-pin PDIP Gull Wing package.

Logic Output Optoisolators Procurement Notes

Verify the specific suffix '320E' against current Broadcom datasheets to confirm package style and RoHS compliance status. Note that this component may be subject to end-of-life restrictions or limited availability. Confirm lead times and alternative sources through authorized distributors as standard stock levels are not guaranteed. Ensure compatibility with existing PCB footprints before finalizing procurement decisions.

Logic Output Optoisolators Selection Notes

Select this component when high-speed digital isolation is required alongside moderate output drive capability. The 50 Mb/s speed makes it suitable for applications where faster optocouplers are unnecessary but standard devices are too slow. Consider the 3750 Vrms isolation rating for safety-critical industrial environments. Evaluate the 10 mA output current against load requirements to ensure sufficient noise margin without exceeding power dissipation limits.

Logic Output Optoisolators Part Context

This part belongs to the HCPL-7723/HCPL-0723 family of high-speed CMOS optocouplers. The HCPL-7723 series represents one of the fastest optocouplers available, setting performance benchmarks for competitors. The '-320E' suffix typically denotes a specific packaging variant, often associated with gull-wing DIP packages, distinguishing it from other pinout or reel configurations within the same functional family.

Logic Output Optoisolators Replacement Considerations

Direct substitutes include HCPL-7723-500E or HCPL-0723 variants depending on package preference. Verify pinout compatibility and electrical specifications such as propagation delay and CMTI before substitution. Ensure the replacement maintains the same isolation voltage rating and output current capabilities to preserve system integrity.
