1 GENERAL DESCRIPTION The SP336E is a monolithic serial multi-transceiver device that contains both RS-232 and RS-485/RS422 line drivers and receivers.
The configuration of the SP336E can be reconfigured into eight operating modes including RS-232 only (4TX/4RX), RS-485/ RS-422 only (2TX/2RX) full or half duplex, two RS232/RS-485 mixed modes.
two shutdown modes and a diagnostic loop-back mode.
Modes may be selected at any time by changing the logic state of the three MODE pins.
The device can implement a dualmode serial port, mixed mode ports or as an interface signal translator.
The MaxLinear charge pumps deliver true RS-232 driver output voltages from a single power supply at either 3.
3V or 5V.
The SP336E requires only four 0.
1F capacitors for charge pump.
A slew rate control pin configures driver outputs for either high data rate or slew-controlled data rates.
Slew-controlled outputs minimize problems with reflections and ringing on long or un-terminated cables.
All RS-485 receivers or transceivers feature high impedance which allow up to 256 transceivers on a shared bus.
When configured in RS-485/RS-422 mode, each driver may be individually enabled or put into tri-state, simplifying use on shared buses or bidirectional communication.
All receivers have advanced failsafe protection to prevent oscillation when inputs are un-connected.
In RS-232 mode each receiver input has a 5k ohm pull-down to ground.
Differential Receivers will default to output logic 1 if inputs are floating, shorted or open but terminated.
All driver outputs and receiver inputs are protected against ESD strikes up to ±15,000 volts.
FEATURES  3.
3V or 5V Single Supply Operation  Robust ±15kV ESD Protection (IEC 61000-4-2 Air Gap)  Software Selectable Mode Selection  Up to 4 Drivers, 4 Receivers RS-232/V.
