CS82C5496

Overview

The CS82C5496 is a CMOS programmable interval timer manufactured by Intersil, part of the 82C54 series. It features three independent 16-bit counters capable of handling clock input frequencies up to 8 MHz. The device operates on a single 5V supply and is housed in a 28-pin PLCC package. Designed for industrial temperature ranges, it provides hardware-compatible replacement for NMOS 8254 timers while offering enhanced performance through advanced CMOS processing.

Feature Summary

• Three independently programmable 16-bit counters
• Maximum clock frequency of 8 MHz
• Industrial temperature range operation
• Single 5V power supply requirement

Applications

• Programmable timing circuits
• Event counter applications
• Square wave generation
• Hardware timer modules for microprocessor systems

Part Context

The CS82C5496 belongs to the 82C54 family of high-performance CMOS programmable interval timers. This series is designed to be pin-compatible with older NMOS 8254 devices, allowing for direct upgrades in existing designs. The '96' suffix typically denotes specific packaging or environmental ratings within the Intersil product line.

Replacement Considerations

The CS82C5496 serves as a drop-in replacement for NMOS 8254 timers due to pin compatibility. Designers should verify that the 8 MHz maximum clock speed meets system requirements, as this is lower than some higher-speed variants like the 82C54-10 or 82C54-12.
