The ADM3202/ADM3222/ADM1385 transceivers are high speed, 2-channel RS-232/V.28 interface devices that operate from a single 3.3 V power supply. Low power consumption and a shutdown facility (ADM3222/ADM1385) make them ideal for battery-powered portable instruments. The ADM3202/ADM3222/ADM1385 parts are available in PDIP, SOIC_N, SOIC_W, SSOP, and TSSOP packages.
The ADM3202/ADM3222/ADM1385 family provides high‑speed, dual‑channel RS‑232/V.28 interfaces that operate from a single 3.3 V supply. Low power consumption and shutdown features make them suitable for battery‑powered portable instruments.
