HS1-1840ARH

HS-1840ARH-T Data Sheet July 1999 File Number 4589.1 Radiation Hardened 16 Channel CMOS Analog Multiplexer with High-Z Analog Input Protection Intersil’s Satellite Applications FlowTM (SAF) devices are fully tested and guaranteed to 100kRAD Total Dose. These QML Class T devices are processed to a standard flow intended to meet the cost and shorter lead-time needs of large volume satellite manufacturers, while maintaining a high level of reliability. The HS-1840ARH-T is a Radiation Hardened, monolithic 16 channel multiplexer constructed with the Intersil Rad-Hard Silicon Gate, Dielectric Isolation process. It is designed to provide a high input impedance to the analog source if device power fails (open), or the analog signal voltage inadvertently exceeds the supply by up to ±35V, regardless of whether the device is powered on or off. Selection of one of sixteen channels is controlled by a 4-bit binary address plus an Enable-Inhibit input, which conveniently controls the ON/OFF operation of several multiplexers in a system. All inputs have electrostatic discharge protection. Features QML Class T, Per MIL-PRF-38535 Radiation Performance - Gamma Dose (γ) 1 x 105 RAD(Si) - No Latch-Up, Dielectrically Isolated Device Islands Improved rDS(ON) Linearity Improved Access Time 1.5µs (Max) Over Temp and Rad High Analog Input Impedance 500MΩ During Power Loss (Open) ±35V Input Over Voltage Protection (Power On or Off) Excellent in Hi-Rel Redundant Systems Break-Before-Mak...
