19-1437; Rev 0; 3/99 15kV ESD-Protected, 3.0V to 5.5V, Low-Power, up to 250kbps, True RS-232 Transceiver ________________General Description The MAX3385E is a 3V-powered EIA/TIA-232 and V.28/V.24 communications interface with low power requirements, high data-rate capabilities, and enhanced electrostatic discharge (ESD) protection. All transmitter outputs and receiver inputs are protected to 15kV using IEC 1000-4-2 Air-Gap Discharge, 8kV using IEC 1000-4-2 Contact Discharge, and 15kV using the Human Body Model. The transceiver has a proprietary low-dropout transmitter output stage, delivering true RS-232 performance from a +3.0V to +5.5V supply with a dual charge pump. The charge pump requires only four small 0.1F capacitors for operation from a +3.3V supply. Each device is guaranteed to run at data rates of 250kbps while maintaining RS-232 output levels. The MAX3385E has two receivers and two drivers. It features a 1A shutdown mode that reduces power consumption and extends battery life in portable systems. Its receivers can remain active in shutdown mode, allowing external devices such as modems to be monitored using only 1A supply current. The MAX3385E is available in a space-saving SSOP package in either the commercial (0C to +70C) or extended-industrial (-40C to +85C) temperature range. ____________________________Features o ESD Protection for RS-232 I/O Pins 15kV--Human Body Model 8kV--IEC 1000-4-2, Contact Discharge 15kV--IEC 1000-4-2, Air-Gap Discharge o Latchup Free o 300A Supply Current o 1A Low-Power Shutdown with Receivers Active o 250kbps Guaranteed Data Rate o 250s Time to Exit Shutdown with 3k Load on V+ o 6V/s Guaranteed Slew Rate o Meets EIA/TIA-232 Specifications Down to 3.0V MAX3385E Ordering Information PART MAX3385ECAP MAX3385EEAP TEMP.
