At initial launch, the family includes four parts: XR33053, XR33152, XR33156 and XR33158. The XR33156 is the most feature-rich ±60V tolerant device on the market with cable invert control to correct for reversed bus pins and a low voltage logic pin, eliminating the need for a level shifter in low voltage applications. Other inherent protection features include ±25V common mode voltage, hot swap glitch protection, overload protection and enhanced receiver fail-safe protection for open, shorted or terminated but idle data lines.
“These transceivers protect against wiring faults up to ±60V and simultaneously protect against ESD events exceeding ±15kV,” said Dale Wedel, Vice President, analogue products, Exar. “This family is a welcome addition to Exar’s rich portfolio of serial transceiver products and enhances our excellent support to our broad industrial customer base.”
The XR33053, XR33152, XR33156 and XR33158 operate over a wide 3 to 5.5V supply voltage range and feature the industry’s lowest standby current of 1uA (max), 1nA (typ). They support data rates up to 20Mbps in either full- or half-duplex configurations, exceed ±15kV ESD protection on the bus pins and operate over the standard industrial temperature range of -40 to 85˚C.
