±15kV ESD-Protected, 10Mbps, 3V/5V,
Quad RS-422/RS-485 Receivers
________________General Description
The MAX3095/MAX3096 are rugged, low-power, quad,
RS-422/RS-485 receivers with electrostatic discharge
(ESD) protection for use in harsh environments. All
receiver inputs are protected to ±15kV using IEC 1000-
4-2 Air-Gap Discharge, ±8kV using IEC 1000-4-2 Contact
Discharge, and ±15kV using the Human Body Model.
The MAX3095 operates from a +5V supply, while the
MAX3096 operates from a +3.3V supply. Receiver prop-
agation delays are guaranteed to within ±8ns of a pre-
determined value, thereby ensuring device-to-device
matching across production lots.
Complementary enable inputs can be used to place the
devices in a 1nA low-power shutdown mode in which
the receiver outputs are high impedance. When active,
these receivers have a fail-safe feature that guarantees
a logic-high output if the input is open circuit. They also
feature a quarter-unit-load input impedance that allows
128 receivers on a bus.
The MAX3095/MAX3096 are pin-compatible, low-power
upgrades to the industry-standard ’26LS32. They are
available in a space-saving QSOP package.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
