MAX485CSA
The MAX481, MAX483, MAX485, MAX487?MAX491, and
MAX1487 are low-power transceivers for RS-485 and RS422 communication. Each part contains one driver and one
receiver. The MAX483, MAX487, MAX488, and MAX489
feature reduced slew-rate drivers that minimize EMI and
reduce reflections caused by improperly terminated cables,
thus allowing error-free data transmission up to 250kbps.
The driver slew rates of the MAX481, MAX485, MAX490,
MAX491, and MAX1487 are not limited, allowing them to
transmit up to 2.5Mbps.

MAX485 is a low power transceivers for RS485 and RS422 communication. MAX485 contains one driver and one receiver. The driver slew rates of the MAX485 are not limited, allowing it to transmit up to 2.5Mbps.
These transceivers draw between 120?A and 500?A of supply current when unloaded or fully loaded with disabled drivers.?MAX485ESA RS422 RS485 IC?operates from a single 5V supply. Drivers are short circuit current limited and are protected against excessive power dissipation by thermal shutdown circuitry that places the driver outputs into a high-impedance state. The receiver input has a fail-safe feature that guarantees a logic-high output if the input is open circuit.
MAX487CSA
The MAX487E and MAX1487E feature quarter-unit-load
receiver input impedance, allowing up to 128 transceivers on the bus. The MAX488E?MAX491E are
designed for full-duplex communications, while the
MAX481E, MAX483E, MAX485E, MAX487E, and
MAX1487E are designed for half-duplex applications.

MAX492CSA
The dual MAX492, quad MAX494, and single MAX495
operational amplifiers combine excellent DC accuracy
with rail-to-rail operation at the input and output. Since
the common-mode voltage extends from VCC to VEE,
the devices can operate from either a single supply
( 2.7V to 6V) or split supplies (?1.35V to ?3V). Each
op amp requires less than 150?A supply current. Even
with this low current, the op amps are capable of driving
a 1k? load, and the input referred voltage noise is only
25nV/?Hz. In addition, these op amps can drive loads in
excess of 1nF.
