|---|---|---|---|---|
| FFF Compatibility | The device features an identical 16-pin SOIC (D) package and shares the exact pin assignments, including the dual global enable controls on pins 4 and 12.The physical dimensions, footprint land pattern, and surface-mount packaging are identical to the original SOIC-16 device.It performs the same RS-422 differential driver function but offers improved CMOS electrical characteristics, lower supply current, and a broader temperature range. | The pinout is fully identical to the target part, with pins 4 and 12 acting as G (active-high) and /G (active-low) global enables respectively.It comes in a standard 16-SOIC surface-mount package with equivalent lead spacing and body dimensions.It meets all TIA/EIA-422-B and ITU V.11 standards, behaving identically under signal transmission while consuming less standby current. | ||
 AI Summary | AM26LS31CDR by Texas Instruments: 4/0 Driver RS422, RS485 16-SOIC. | The AM26C31IDR is the official CMOS upgrade family member from the same manufacturer. It is a drop-in replacement that retains the identical pin assignment and function while providing superior thermal, power, and supply range performance.
| The ST26C31BDR is a high-reliability second-source replacement from STMicroelectronics. It matches the original's pinout and functional characteristics entirely while offering CMOS efficiency and industrial temperature grades.

You searched one part. Parter watches your whole BOM.
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.
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.
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.
