MAXIM MAX3095, MAX3096 User Manual

________________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 1000­4-2 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 prop­agation delays are guaranteed to within ±8ns of a pre­determined 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.
