• Integrates four independent driver and receiver pairs within a single package
• Features Schmitt trigger inputs for improved signal integrity and noise rejection
• Designed specifically for high-speed bus organized data transmission applications

Applications

• Bus organized data transmission systems
• General purpose line interfacing
• High-speed digital communication buses

Procurement Notes

Verify the specific suffix designation against the original manufacturer's documentation to ensure exact functional equivalence. Confirm that the 16-pin DIP package dimensions match the target board layout requirements. Check for any environmental compliance markings or lead-free status updates provided by Rochester Electronics for this re-introduced part number.

Selection Notes

Select this component when a quad bus transceiver with Schmitt trigger inputs is required for noisy environments. Ensure the system voltage levels are compatible with the standard logic supply requirements. Verify that the 16-pin DIP form factor fits the available footprint constraints on the printed circuit board design.

Part Context

Rochester Electronics re-introduces critically needed semiconductors with full authorization from the original manufacturer. This product continues the lineage of the DS7838 series, maintaining quality standards that meet or exceed the original components. It serves legacy systems requiring discontinued interface chips.

Replacement Considerations

Compatible variants include DS7838J, DS8838J, and DS8838M. Verify pinout compatibility before substitution.
