FEATURES:
four transceivers device Independent driver/receiver enables Mbps data rate Full duplex operation quiescent current (<300µA transceiver) Current limiting thermal shut-down driver overload protection single event latch-up Total dose hardened Krads (Si) depending orbit duration mission leaded flatpack (422DRH) leaded flatpack (422QRH)
DESCRIPTION:
SEi422DRH SEi422QRH dual quad, power, full duplex transceivers RS-422 space communications. Each device contains multiple drivers receivers. SEi422D/Q2.5RH slew rate limited, allowing data rates Mbps. drivers short-circuit current limited protected against excessive power dissipation thermal shut-down circuitry that places driver outputs into high impedance state. receiver inputs have fail-safe feature that guarantees logic-high output input open circuited. SEi422D/Q2.5RH transceivers feature typical Krads (Si) total dose tolerance depending upon orbit duration mission. SEi422D/Q2.5RH intended environments encountered high reliability spacecraft applications. patented radiation-hardened RAD-PAK® technology incorporates radiation shielding microcircuit package. Capable surviving in-space environments, SEi422D/Q2.5RH ideal satellite, spacecraft, space probe missions.
