max3095, max3096 ±15kv esd保护、10mbps、3v/5v、四路rs-422/rs-485接收器
概述
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 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.
