Programmable Timers And Oscillators Part Context

This part belongs to the Harris 82C54 family of programmable interval timers. The 'IP' suffix typically denotes the industrial temperature grade (-40°C to +85°C) and plastic DIP packaging. Harris Corporation was a primary manufacturer of this component before its semiconductor assets were acquired by Intersil, which continues to produce equivalent parts like the MR82C54 series.

Programmable Timers And Oscillators Replacement Considerations

Direct pin-compatible replacements include the Intersil MR82C54-10B and IDT CA82C54-5IP. When substituting, verify that the replacement component meets the specific industrial temperature requirements (-40°C to +85°C) and voltage specifications (5V). Ensure the package type matches the original design constraints.
