ID82C86H

Overview

The ID82C86H is an octal bus transceiver manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 4.5 V to 5.5 V and supports data rates up to 1 Mb/s. The device features three-state outputs and is housed in a 20-pin PDIP package. It functions as a bidirectional interface for CMOS logic systems, providing gated inputs that eliminate the need for external pull-up resistors. The component is designed for industrial temperature ranges, typically operating between -40°C and +85°C.

Feature Summary

• Octal bus transceiver architecture with true output polarity
• Gated inputs remove requirement for external pull-up resistors
• Three-state output capability for efficient bus management
• Bidirectional data transfer functionality

Applications

• CMOS logic bus interfacing
• Industrial control system data transmission
• Microprocessor peripheral expansion

Procurement Notes

Verify RoHS compliance status prior to procurement, as historical documentation indicates non-compliance for certain variants. Confirm package authenticity and pin alignment against the 20-pin PDIP specification. Ensure the supplier provides traceable manufacturing origin records to validate the Renesas or Intersil branding. Request updated environmental declarations if current regulatory standards are mandatory for the target application.

Selection Notes

Select this component when designing systems requiring high-density octal data buffering with minimal external circuitry. The integrated gating feature simplifies board layout by removing pull-up components. Verify that the required data rate does not exceed 1 Mb/s and that the operating environment falls within the specified temperature limits. Consider the through-hole mounting style if PCB space allows for larger packages compared to surface-mount alternatives.

Part Context

This part belongs to the legacy 82C series of interface components originally developed by Intersil and later acquired by Renesas. It serves as a CMOS-compatible successor to earlier NMOS bus transceivers, offering lower power consumption while maintaining electrical compatibility with standard TTL and CMOS logic families. The component represents a mature technology node used in established industrial and legacy computing architectures.
