Product Summary
The max202 is a 5V RS-232 transceiver. It is designed for RS-232 and V.28 communication interfaces where ±12V supplies are not available. On-board charge pumps convert the +5V input to the Q10V needed for RS-232 output levels. The max202 operates from +5V and +12V, respectively, and contain a +12V to -12V charge-pump voltage converter. The drivers maintain the ±5V EIA/TIA-232E output signal levels at data rates in excess of 120kbps when loaded in accordance with the EIA/TIA-232E specification. Applications of the max202 include: Computers: Laptops, Palmtops, Notebooks; Battery-Powered Equipment; Handheld Equipment.
