ID82C54

Programmable Timers And Oscillators Overview

The ID82C54 is a CMOS programmable interval timer manufactured by Renesas Electronics, belonging to the 82C54 series. It integrates three independent 16-bit counters capable of handling clock input frequencies up to 8MHz. The device operates within a supply voltage range of 4.5V to 5.5V and features a maximum propagation delay of 150 ns. Designed for industrial applications, it supports an operating temperature range from -40°C to +85°C. The component is housed in a 24-pin Ceramic Dual In-Line Package (CDIP-24) and utilizes through-hole mounting technology.

Programmable Timers And Oscillators Feature Summary

• Compatible with standard industry processors

Programmable Timers And Oscillators Applications

• Timing and counting circuits in industrial control systems
• Clock generation for microprocessor-based designs
• Programmable interval timing functions

Programmable Timers And Oscillators Procurement Notes

Verify package authenticity as the ID82C54 uses a ceramic dual in-line package (CDIP-24), which differs from plastic variants like the CP82C54Z. Confirm moisture sensitivity levels and storage conditions prior to assembly. Check for RoHS compliance status specific to the manufacturing batch, as older production runs may vary. Ensure ordering quantities align with tube packaging standards typically associated with this form factor.

Programmable Timers And Oscillators Selection Notes

Select the ID82C54 when a ceramic package is required for enhanced durability or thermal performance compared to plastic alternatives. This model supports up to 8MHz clock frequency; choose the IS82C54-10Z or CD82C54-12 if higher speeds are needed. Verify that through-hole mounting is feasible on the target PCB design. Compare against the MD82C54/B if military-grade qualification (MIL-STD-883) is necessary for the application environment.

Programmable Timers And Oscillators Part Context

The ID82C54 is part of the broader 82C54 family of programmable timers produced by Renesas (formerly Intersil). It serves as the ceramic DIP variant of the widely used 82C54 architecture. Other family members include the PLCC versions (IS82C54Z96) and plastic DIP versions (CP82C54Z). The device is functionally compatible with NMOS 8254 equivalents but offers improved CMOS performance characteristics.

Programmable Timers And Oscillators Replacement Considerations

For direct pin-compatible replacements, consider the IS82C54Z96 (PLCC-28) if package adaptation is possible, or the CD82C54-12 for higher speed requirements (12MHz). The MD82C54/B offers similar functionality with military qualification in a CERDIP package.
