Procurement Notes

Verify the suffix 'P' indicates the PDIP-8 package variant distinct from surface-mount options. Confirm RoHS compliance status through official documentation. Ensure the specific revision matches design requirements. Validate pinout compatibility during integration. Check for automotive-grade NCV prefix availability if site controls are required.

Selection Notes

Select this part for applications requiring dual-channel isolation with high slew rates. The non-inverting configuration simplifies control logic interfacing. Consider thermal management due to power dissipation limits. Verify input signal levels against CMOS/LSTTL thresholds. Evaluate load capacitance to ensure rise/fall time specifications are met under operating conditions.
