±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.
