FFF CompatibilityExact pin-for-pin compatible drop-in replacement in the same 28-SOIC Wide (SW) package.Identical package dimensions and footprint, requiring no board layout changes.Exact functional match, operating from 5V with the same transceiver configuration (5-Driver/3-Receiver) and shutdown features.Same pin layout adjustments as LTC1338CSW#PBF are required due to reversed C2 capacitor pins (26 and 27) and differing control pin logic on pins 13 and 16.Fits on the same physical 28-SOIC Wide land pattern.Provides equivalent 5-Driver/3-Receiver RS232 transceiver performance with enhanced temperature tolerance.
AI Summary

LT1138ACSW by Analog Devices: 5/3 Transceiver Full RS232 28-SOIC.

This is the direct lead-free (RoHS compliant) equivalent of the original LT1138ACSW transceiver. It is currently active, sharing identical pin assignments, electrical performance, and packaging.

  • Direct lead-free drop-in replacement for the queried part
  • Same physical footprint and package: 28-SOIC (0.295 inch width)
  • Identical electrical performance and 120/250 kbaud data rate specifications

This alternative is the industrial temperature grade version of the LTC1338 series. It offers broader thermal operating margins but shares the same minor board adjustment requirements on the charge pump capacitor and control pins as its commercial counterpart.

  • Extended industrial temperature range of -40°C to +85°C vs commercial 0°C to +70°C
  • Active lifecycle status providing robust secondary sourcing
  • Identical 28-SOIC footprint with 5-Driver/3-Receiver configuration
  • Charge pump capacitor pins 26 and 27 are reversed compared to the LT1138A
  • Control pin configurations and shutdown logic differ on pins 13 and 16

You searched one part. Parter watches your whole BOM.

  1. All your BOM, at once

    Parter maps every line to live stock, lead time, lifecycle and compliance data across the entire market — not part by part.

  2. Hear about problems before they hit production

    Allocation, EOL and last-time-buy notices surface the moment they appear, not when your buyer's PO bounces.

  3. Qualified replacements in minutes, not days

    Every at-risk line gets form-fit-function matches like the ones above — deltas flagged, evidence attached. Review, push to your BOM, and Parter starts watching the new part too.
