General Description
The MAX200-MAX211/MAX213 transceivers are 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 ± 10V needed for RS-232 output levels. The MAX201 and MAX209 operate from +5V and +12V, and contain a +12V to -12V charge-pump voltage converter.
The MAX200-MAX211/MAX213 drivers and receivers meet all EIA/TIA-232E and CCITT V.28 specifications at a data rate of 20kbits/sec. The drivers maintain the ± 5V EIA/TIA-232E output signal levels at data rates in excess of 120kbits/sec when loaded in accordance with the EIA/TIA-232E specification.
The 5µW shutdown mode of the MAX200, MAX205, MAX206, and MAX211 conserves energy in battery-powered systems. The MAX213 has an active-low shutdown and an active-high receiver enable control. Two receivers of the MAX213 are active, allowing ring indicator (R1) to be monitored easily using only 75µ power.
The MAX211 and MAX213 are available in a 28-pin wide small-outline (SO) package, and a 28-pin shrink small-outline package (SSOP), which occupies only 40% of the area of the SO. The MAX207 is now available in a 24-pin SO package and a 24-pin SSOP. The MAX203 and MAX205 use no external components, and are recomended for applications with limited circuit board space.
