The MAX3222/MAX3232/MAX3237/MAX3241 transceivers
have a proprietary low-dropout transmitter output stage
enabling true RS-232 performance from a 3.0V to 5.5V
supply with a dual charge pump. The devices require only
four small 0.1µF external charge-pump capacitors. The
MAX3222, MAX3232, and MAX3241 are guaranteed to
run at data rates of 120kbps while maintaining RS-232
output levels. The MAX3237 is guaranteed to run at data
rates of 250kbps in normal operating mode and 1Mbps in
the MegaBaud™ operating mode.
The MAX3222/MAX3232 have 2 receivers and 2 drivers.
The MAX3222 and MAX3232 are pin, package, and functionally compatible with the industry-standard MAX242
and MAX232, respectively.
The MAX3241 has 5 receivers and 3 drivers, while the
MAX3237 has 3 receivers and 5 drivers. Receivers R1
(MAX3237/MAX3241) and R2 (MAX3241) have extra
outputs in addition to their standard outputs. These extra
outputs are always active, allowing external devices to be
monitored without forward biasing the protection diodes in
circuitry that may have VCC completely removed.
The MAX3222, MAX3232, and MAX3241 are available in
space-saving TSSOP and SSOP packages with operating
temperatures of either -40°C to +85°C or 0°C to 70°C.
