+3.0V to+5.5V, 1µA, RS-232/

RS-485/422 Multiprotocol Transceivers

General Description

The MAX3160/MAX3161/MAX3162 are programmable

+3V to +5.5V RS-232/RS-485/422 multiprotocol trans-

ceivers. The MAX3160/MAX3161 are pin programmable

as a 2TX/2RX RS-232 interface or a single RS-485/422

transceiver. The MAX3162 is configured as a 2TX/2RX

RS-232 interface and a single RS-485/422 transceiver

simultaneously.

All devices incorporate a proprietary low-dropout trans-

mitter output stage and an on-board dual charge pump

to allow RS-232 and RS-485/422 compliant perfor-

mance from a +3V to +5.5V supply. These devices also

feature pin-selectable transmitter slew rates for both

RS-232 and RS-485/422 modes. Slew-rate limiting mini-

mizes EMI and reduces reflections caused by improp-

erly terminated cables, allowing error-free data

transmission up to 250kbps. Disabling slew-rate limiting

allows these devices to transmit at data rates up to

10Mbps in RS-485/422 mode and up to 1Mbps in RS-

232 mode.

The MAX3160/MAX3162 offer a flow-through pinout that

facilitates board layout. The MAX3160/MAX3161/

MAX3162 are available in tiny SSOP packages and

operate from -40°C to +85°C.
