IS82C5496

Programmable Timers And Oscillators Overview

The IS82C5496 is a CMOS programmable interval timer manufactured by Renesas Electronics. It features three independent 16-bit counters capable of handling clock input frequencies up to 8 MHz. The device operates on a single 5V power supply with a voltage range of 4.5 V to 5.5 V. It supports six programmable timer modes and includes status read-back commands. The component is housed in a 28-pin PLCC package and is rated for an industrial operating temperature range from -40°C to +85°C.

Programmable Timers And Oscillators Procurement Notes

The IS82C5496 is listed as a discontinued product by the manufacturer. Availability is limited to existing stock or surplus channels. Verification of authenticity and storage history is critical due to the component's end-of-life status. Buyers should confirm moisture sensitivity levels and lead integrity before procurement.

Programmable Timers And Oscillators Selection Notes

Select the IS82C5496 when an 8 MHz clock speed is sufficient for the application; higher speed variants like the IS82C54-10 (10 MHz) are available if needed. Ensure the design accommodates the 28-PLCC surface mount package. Verify that the 5V logic levels and TTL compatibility meet the system interface requirements.

Programmable Timers And Oscillators Part Context

This part belongs to the 82C54 series of CMOS programmable timers, which serve as enhanced versions of the NMOS 8253. The '96' suffix typically denotes the specific speed grade (8 MHz) and industrial temperature range variant within the Renesas/Intersil portfolio.

Programmable Timers And Oscillators Replacement Considerations

Direct pin-compatible replacements include the IS82C54Z96 (8 MHz) and IS82C54-1096 (10 MHz). For non-CMOS legacy designs, the NMOS 8254 is functionally compatible but requires different power and timing considerations.
