  1. SP336E Dual Protocol

  2. SP336 Key Features • Low cost • Software dual protocol control • Mixed protocol operation • Software tri-state control • Full or half duplex operation • Individual driver and receiver enable controls • Diagnostic loop-back function • True failsafe operation • 1/8th unit load or up to 256 nodes on a bus • Software slew rate control • 28 TSSOP or SOIC packaging

  3. Dual Protocol (SP33x) • SP331 and SP332 – 4Tx/4Rx RS232 or 2Tx/2Rx RS485 • Configure as 4Tx/4Rx RS232 or 2Tx/2Rx RS485 or mix RS232/RS485 • SP331 configurable for RS232 or RS485 or mixed • SP332 has Loopback pin and shutdown pin • SP334 – 3Tx/5Rx RS232 or 2Tx/2Rx RS485 • SP336E • 4Tx/4Rx RS232 or 2Tx/2Rx RS485 • 3V to 5V operation • ±15kV ESD protection • Full or Half Duplex, Advanced Failsafe, 1/8th Load RS485 • 250kbps or 1Mbps RS232. 250kbps or 10Mbps RS485

  4. SP336E Configurable RS232/485 • Configurable into 8 Modes • RS-232 with 4 channels • RS-485 full or half duplex, 2-ch. • Combo RS-232/485 half or full duplex • Diagnostic loop-back • Low-power standby mode • Tri-state, full-shutdown • 3V to 5V single supply • 15kV ESD protection • Improved signal integrity • 250k, or 1 & 10 Mbps data rates • Adjustable slew for EMI control • RS-485 failsafe and 1/8th unit load RS232 4T/4R RS232 2T/2R + RS485 1T/1R F-Dplx Full Shut-down Mode RS485 2T/2R F-Dplx Loop-Back Mode RS232 2T/2R + RS485 1T/1R H-Dplx Shut-down with Rx Active RS485 2T/2R H-Dplx

  5. SP336 Dual Protocol Applications • Point-of-Sales Equipment • Industrial Controls • Protocol Translators • Cable Repeaters / Port Extenders / Hubs • Peripherals • Networking • Security Systems • Flexible serial ports configurable as RS-232, RS-485 or RS-422

  6. Upgrade to the SP336E • Upgrade from existing SP331, SP332, SP334, • Compatible pinout and package • Now with +/-15kV ESD protection • Now capable of 3.3V operation • Advanced failsafe receiver protection • Capable of either full-duplex or half-duplex • Adjustable Slew/Speed control • Upgrade from competitor devices • Superior alternative to LTC1334, MAX3160-62, AD7306 • Replaces older Exar devices SP522, SP524 • Single power supply solution • Eliminates power sequencing requirements

  7. Feature Comparison

  8. Specification Comparison

  9. SP336 Competitive Edge • Competition • Maxim MAX3162 • SP336 Advantage • More channels • More configurations • Lower power • Diagnostic loop back • Enhanced ESD • Thinner package • NET1/Net2 and TBR-1 TBR-2 Certified
