RS-232 transceiver, 3/3 config, 460 Kbps
The ADM3312EACPZ is a 3-driver, 3-receiver RS-232 transceiver from Analog Devices, running full duplex at 460 Kbps. Receiver hysteresis is 140 mV, which cleans up marginal signals on long cable runs — the threshold margin prevents chatter when the cable picks up common-mode noise from nearby switching supplies.
Package and board-fit — 32-LFCSP 5x5
Housed in a 32-lead LFCSP (5 mm × 5 mm) with an exposed thermal pad, the ADM3312EACPZ requires a thermal-land pattern on the PCB for heat sinking. The package is supplied in tray format — not tape-and-reel. If your pick-and-place line is set up for tape-fed only, the ADM3312EARUZ-REEL7 variant (same die, TSSOP package, reel packaging) is the alternative. Confirm the PCB footprint before swapping: LFCSP and TSSOP have different land patterns.
