TP82C54-2

Overview

The TP82C54-2 is a programmable interval timer manufactured by Rochester Electronics, LLC, utilizing advanced CHMOS III technology. It features three independent 16-bit counters and supports six programmable modes for flexible timing applications. The device operates on a parallel direct address interface with an 8-bit external data bus width. It functions within a supply voltage range of 4.5 V to 5.5 V, with a maximum clock frequency of 8 MHz. The component is housed in a 24-pin DIP package (R-PDIP-T24) and is rated for operation between -40 °C and 85 °C.

Procurement Notes

Verify the specific manufacturer origin and lot traceability upon receipt, as Rochester Electronics sources components from various authorized manufacturers. Confirm that the device matches the required pinout and electrical specifications for your design. Ensure proper handling procedures are followed during installation to maintain component integrity.

Selection Notes

Select this component when a robust, multi-channel programmable timer is required for industrial or commercial environments. Consider the 8 MHz maximum clock speed and the wide temperature range (-40 °C to 85 °C) for suitability in demanding conditions. Verify that the 24-pin DIP package fits the available board space and assembly constraints.

Part Context

This part belongs to the family of CMOS programmable interval timers, originally based on designs such as the Intel 82C54. Rochester Electronics provides these components as a continuous source, often serving as a replacement for obsolete original equipment manufacturer parts. The TP82C54-2 variant specifically denotes the enhanced CHMOS III technology implementation.

Replacement Considerations

The TP82C54-2 serves as a functional equivalent to the Intel 82C54. When substituting, verify that the pin configuration and electrical characteristics align with the original design requirements to ensure seamless integration without hardware modifications.
