| 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.
