MAXIM'S +3.3V RS-485/RS-422 TRANSMITTER UPGRADES TO THE INDUSTRY-STANDARD 75174, 34C87, AND 26LS31 ARE IDEAL FOR TELECOM APPLICATIONS
SUNNYVALE, CA-November 7, 2002-Maxim Integrated Products (NASDAQ: MXIM) introduces the MAX3030E-MAX3033E quad, RS-422, ESD-protected transmitters. Optimized for parallel data transmission in telecom applications, these devices are pin-compatible upgrades to the industry-standard 75174, 34C87, and 26LS31 products. The hot-swap feature allows live insertion of the device without erroneous data transfer. Hot insertion is achieved by holding the output drivers in a high-impedance state until the first transition on driver enable.
The MAX3030E-MAX3033E operate from a single +3.3V supply and consume less than 100µA of quiescent supply current. The MAX3030E/MAX3032E are optimized for data rates up to 20Mbps. The MAX3031E/MAX3033E feature slew-rate limiting to minimize EMI emissions and reduce reflections, allowing error-free data transmission up to 2Mbps. All transmitter output pins are protected to ±15kV per the Human Body Model.
The MAX3030E-MAX3033E are available in the commercial and extended temperature ranges in a 16-pin narrow SO and a space-saving 16-pin TSSOP. Prices start at $0.73 (1000-up, FOB USA).
