CA139 overview

CA139 is a component documented by Intersil Corporation. The PDF description identifies it as "Quad Voltage Comparators for Industrial, Commercial and Military Applications October 1999." This guide condenses the most useful engineering information from the available PDF so that designers and sourcing teams can identify the checks that still need confirmation in the original document.

Specifications and operating details

The following points were extracted from the PDF text. Check the associated conditions, notes and limits in the complete document before using a value in a design.

  • Inputs must not go more negative than -0.3V.
  • The maximum output current independent of V+ is approximately 20mA.
  • Electrical SpecificationsV+ = 5V, Unless Otherwise Specified PARAMETER SYMBOL TEST CONDITIONS TEMP (oC) CA139 CA139A UNITSMIN TYP MAX MIN TYP MAX Input Offset Voltage V IO VREF = 1.4V, RS = 0, Output Switch Point V ≅ 1.4V TA = 25 - 2 5 - 1 2.
  • Ambient Temperature (TA) applicable over operating temperature range as shown below.
  • The comparator will provide a proper output state even if the positive swing of the inputs exceeds the power supply voltage level, if the other input remains within the common mode voltage range.
  • The low input voltage state must not be less than -0.3V (or 0.3V below the magnitude of the negative power supply, if used).
  • The upper end of the common mode voltage range is (V+) - 1.5V, but either or both inputs can go to +30V without damage.

Topics covered by the datasheet

The document includes sections related to:

  • Features
  • Applications
  • Ordering Information

Engineering review checklist

  • Check resistance value, tolerance, temperature coefficient and long-term stability over the operating range.
  • Derate continuous power for ambient temperature and verify pulse or surge capability separately.
  • Match the land pattern, termination finish and current-sense routing to the exact package option.

Always confirm values against the latest manufacturer-controlled datasheet, especially when qualifying a substitute or releasing a production BOM.
