The ADM3061E/ADM3062E/ADM3063E/ADM3064E/ADM3065E/

ADM3066E/ADM3067E/ADM3068E are 3.0 V to 5.5 V, IEC electro-

static discharge (ESD) protected RS-485 transceivers, allowing the

devices to withstand ±12 kV contact discharges on the transceiver

bus pins without latch-up or damage. The ADM3062E/ADM3064E/

ADM3066E/ADM3068E feature a VIO logic supply pin that allows a

flexible digital interface capable of operating as low as 1.62 V.

The ADM3065E/ADM3066E/ADM3067E/ADM3068E are suitable

for high speed, 50 Mbps, bidirectional data communication on mul-

tipoint bus transmission lines. ADM3061E/ADM3062E/ADM3063E/

ADM3064E/ADM3065E/ADM3066E/ADM3067E/ADM3068E fea-

ture a 1/4 unit load input impedance that allows up to 128

transceivers on a bus. The ADM3061E/ADM3062E/ADM3063E/

ADM3064E models offer all of the same features as the

ADM3065E/ADM3066E/ ADM3067E/ADM3068E models at a low

500 kbps data rate that is suitable for operation over long cable

runs.

The ADM3061E/ADM3062E/ADM3065E/ADM3066E are half-du-

plex RS-485 transceivers, fully compliant to the PROFIBUS® stand-

ard with increased 2.1 V bus differential voltage at VCC ≥ 4.5 V.

The ADM3063E/ADM3064E/ADM3067E/ADM3068E are full duplex

RS-485 transceiver options.

The RS-485 transceivers are available in a number of space-sav-

ing packages, including the 10-lead, 3 mm × 3 mm lead frame

chip-scale package (LFCSP); the 8‑lead or 10-lead, 3 mm × 3 mm

mini small outline package (MSOP); and the 8-lead or 14-lead,

narrow-body standard small outline packages (SOIC_N). Models

with operating temperature ranges of −40°C to +125°C and −40°C

to +85°C are available.

Excessive power dissipation caused by bus contention or by output

shorting is prevented by a thermal shutdown circuit. If a significant

temperature increase is detected in the internal driver circuitry

during fault conditions, this feature forces the driver output into a

high impedance state.

The ADM3061E/ADM3062E/ADM3063E/ADM3064E/ADM3065E/

ADM3066E/ADM3067E/ADM3068E guarantee a logic high receiver

output when the receiver inputs are shorted, open, or connected to

a terminated transmission line with all drivers disabled.

the ADM3061E/ADM3062E/ADM3063E/ADM3064E/ADM3065E/

ADM3066E/ADM3067E/ADM3068E data rate capability across

temperature, power supply, and package options. Refer to the

Evaluation Boards section for model numbering.

1 The ADM3065E/ADM3066E/ADM3067E/ADM3068E data input (DI) transmits 50 Mbps (or 500 kbps for the ADM3061E/ADM3062E/ADM3063E/ADM3064E) clock data,

and the ADM3061E/ADM3062E/ADM3063E/ADM3064E/ADM3065E/ADM3066E/ADM3067E/ADM3068E driver enable (DE) is enabled for 50% of the DI transmit time.
