+5V RS-232 Transceivers with 0.1uF External Capacitors - Maxim
Description
MAX200–MAX209/ MAX211/MAX213
+5V, RS-232 Transceivers with 0.
1μF External Capacitors
General Description
MAX200-MAX209, MAX211, and MAX213 are a family of RS-232 and V.
28 transceivers with integrated charge pump circuitry for single +5V supply operation.
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 MAX211 and MAX213 are available in a 28-pin, wide small-outline (SO) package and a 28-pin shrink smalloutline (SSOP) package, which occupies only 40% of the area of the SO.
The MAX207 is available 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.
Benefits and Features
●● Saves Board Space • Integrated Charge Pump Circuitry Eliminates the Need for a Bipolar ±12V Supply Enables Single Supply Operation From Either +5V or 9V to +12V
• Integrated 0.
1μF Capacitors (MAX203, MAX205) • 24 pin SSOP Package Saves Up to 40% Versus
SO Package ●● Saves Power for Longer Battery Operation
• 5μW Shutdown Mode (MAX200, MAX205, MAX206, MAX211)
• 75μW Ring Indicator Monitoring with Two Active Receivers (MAX213)
Applications
●● Battery-Powered Equipment ●● Handheld Equipment ●● Portable Diagnostics Equipment
