CS82C86H-5

Overview

The Harris CS82C86H-5 is an octal bus transceiver belonging to the CMOS logic series. It features a single functional unit with eight bits of data width and true output polarity. The device utilizes a common control mechanism for bidirectional data transfer across two ports. It is housed in a plastic quad flat package with twenty terminals (PQCC20). The component supports three-state outputs and includes gated inputs to eliminate the need for external pull-up resistors. It operates within a temperature range of -40°C to +85°C and has a maximum load capacitance of 300 pF.

Feature Summary

• Gated inputs eliminate the need for pull-up resistors
• Bidirectional data transfer capability
• Three-state output configuration

Applications

• Microprocessor system data bus interfacing
• Bidirectional memory buffer applications
• I/O port expansion circuits

Procurement Notes

Verify the specific suffix designation against manufacturer documentation to confirm the exact package type and temperature grade, as variations exist between ceramic and plastic enclosures. Confirm RoHS compliance status, as older Harris CMOS parts may not meet current environmental standards. Ensure the sourcing channel provides original manufacturer datasheets to validate pinout compatibility and electrical characteristics before integration into design schematics.

Selection Notes

Select this component when designing systems requiring high-speed bidirectional data transfer with low power consumption. The CMOS technology offers performance comparable to bipolar equivalents while reducing power dissipation. Consider the PQCC20 package constraints for PCB layout. Verify that the system voltage levels align with standard CMOS logic requirements and that the operating temperature range meets the environmental conditions of the final application.

Part Context

This part belongs to the Harris 82C86 family of octal bus transceivers, which are CMOS versions of the classic 8286 bipolar interface chip. The family provides industry-standard compatibility for connecting microprocessors to peripheral devices or memory. Harris Corporation manufactured these components using advanced silicon gate CMOS processes to achieve higher speeds and lower power than previous generations.
