________________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.
