The MAX200-MAX211/MAX213 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 20kbps. 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. The 5µW shutdown mode of the MAX200, MAX205, MAX206, and MAX211 conserves energy in battery- powered systems. The MAX213 has an active-low shut- down and an active-high receiver enable control. Two receivers of the MAX213 are active, allowing ring indica- tor (RI) to be monitored easily using only 75µW power. The MAX211 and MAX213 are available in a 28-pin wide small-outline (SO) package and a 28-pin shrink small-outline (SSOP) package, which occupies only 40% of the area of the SO. The MAX207 is now avail- able in a 24-pin SO package and a 24-pin SSOP. The MAX203 and MAX205 use no external components, and are recommended for applications with limited circuit board space.
The MAX200‑MAX211/MAX213 family are 5 V RS‑232 and V.28 transceivers that generate the required ±10 V RS‑232 levels using on‑board charge‑pump converters. They meet EIA/TIA‑232E and CCITT V.28 specifications at data rates up to 120 kbps and include shutdown modes for low‑power operation.
The devices are offered in 28‑pin SO and SSOP packages, support a wide operating temperature range, and provide features such as auto‑shutdown, receiver enable control, and low‑leakage shutdown currents (<1 pA). Ordering information, package dimensions, and detailed electrical characteristics are provided throughout the sheet.
