MAX13412EESA+T

Technical Specifications

Product Introduction

Features

• The MAX13410E–MAX13415E are half-duplex RS-485-/RS422-compatible transceivers optimized for isolated applications.
• These devices feature an internal low-dropout regulator (LDO), one driver, and one receiver.
• The internal LDO allows the part to operate from an unregulated power supply of up to 28V.
• The AutoDirection feature reduces the number of optical isolators needed in isolated applications.
• Other features include enhanced ESD protection, fail-safe circuitry, slew-rate limiting, and fullspeed operation.
• The MAX13410E–MAX13415E internal LDO generates a 5V±10% power supply that is used to power its internal circuitry.
• The MAX13412E–MAX13415E bring the 5V to an output VREG that allows the user to power additional external circuitry with up to 20mA to further reduce external components.
• The MAX13410E/MAX13411E do not have a 5V output and come in industry-compatible pinouts.
• The MAX13410E–MAX13415E feature a 1/8-unit load receiver input impedance, allowing up to 256 transceivers on the bus.
• All driver outputs are ESD protected using the Human Body Model.
• These devices also include fail-safe circuitry (MAX13410E/MAX13411E/ MAX13414E/MAX13415E only), guaranteeing a logic-high receiver output when the receiver inputs are open or shorted.
• The receiver outputs a logic-high when the transmitter on the terminated bus is disabled (high impedance).
• The MAX13412E/MAX13413E feature Maxim’s proprietary AutoDirection control.
• This architecture eliminates the need for the DE and RE control signals.
• In isolated applications, this reduces the cost and size of the system by reducing the number of optical isolators required.
• The MAX13410E/MAX13412E/MAX13414E feature reduced slew-rate drivers that minimize EMI and reduce reflections caused by improperly terminated cables, allowing error-free transmission up to 500kbps.
• The MAX13411E/MAX13413E/MAX13415E are not slew-rate limited, allowing transmit speeds up to 16Mbps.
• The MAX13410E–MAX13415E are available in an 8-pin SO package with an exposed paddle to improve power dissipation, and operate over the extended -40℃ to +85℃ temperature range.
• Wide +6V to ±28V Input Supply Range
• +5V Output Supplies Up to 20mA to External Circuitry
• Internal LDO
• Low 65μA (typ) Shutdown Supply Current
• Extended ESD Protection ±15kV Human Body Model (MAX13412E/ MAX13413E) ±14kV Human Body Model (MAX13410E/ MAX13411E)
• 1/8-Unit Load, Allowing Up to 256 Transceivers on the Bus
• 40℃ to +85℃ Operating Temperature Range
• Fail-Safe
• Slew-Rate Limited and Full-Speed Versions
• Up to 16Mbps Data Rate on Full-Speed Versions
