Procurement Notes

Verify the obsolete status of the EL7232CN before procurement planning. Confirm package availability and lead times through authorized distributors. Ensure design-in decisions account for end-of-life implications and potential need for long-term supply agreements or alternative sourcing strategies.

Selection Notes

Select this component for applications requiring high-speed signal transmission with 3-state bus control. Consider the 4.5V to 16V operating range and 2A peak drive capability for driving capacitive loads. Verify compatibility with system voltage levels and thermal requirements within the -40°C to +85°C temperature range.

Part Context

The EL7232 belongs to a family of high-speed line drivers including EL7202, EL7212, and EL7222. These devices utilize proprietary Turbo-Driver circuitry for improved speed and drive capability into highly capacitive loads. The family offers matched rise and fall delay times to reduce timing errors and clock skew problems compared to standard CMOS devices.
