CS82C87H-5

Overview

The CS82C87H-5 is an octal inverting bus transceiver fabricated using CMOS technology. It provides bidirectional data transmission across two ports with 8-bit width per element. The device features 3-state outputs and operates within a supply voltage range supporting 8mA output high current and 20mA output low current. It is available in a 20-pin PLCC package (9x9 mm) and supports commercial, industrial, and military temperature ranges.

Feature Summary

• Octal inverting bus transceiver for bidirectional data transfer
• CMOS fabrication process ensuring low power consumption
• 3-state output capability for efficient bus sharing
• Gated inputs eliminate the need for external pull-up resistors

Applications

• Bidirectional data transmission in microprocessor systems
• Memory interface circuits requiring inverting logic
• Bus-oriented architectures with 3-state control requirements

Procurement Notes

Verify the specific suffix 'H' and '-5' to confirm the inverting function and extended temperature range availability. Confirm the package type matches the required 20-pin PLCC footprint. Ensure compatibility with the target system's voltage levels and load capacitance specifications before integration.

Selection Notes

Select this component when an inverting octal transceiver is required for bidirectional data paths. The CMOS construction offers advantages in power efficiency compared to older TTL equivalents. Consider the 3-state output feature if multiple devices share the same bus lines. Verify that the inverting polarity aligns with the system logic design requirements.

Part Context

This part belongs to the Harris 82C87 series of bus transceivers. It is an enhanced version utilizing advanced CMOS processes. The series includes non-inverting variants like the 82C86. The CS82C87H-5 specifically denotes the inverting function with extended environmental ratings.

Replacement Considerations

Compatible substitutes include the standard 82C87H or equivalent octal inverting bus transceivers from other manufacturers. Ensure pinout compatibility with the 20-PLCC package. Verify that replacement parts support the same 3-state output characteristics and voltage levels.
