HS-1840RH/883S中文资料Rad-Hard 16 Channel CMOS Analog Multiplexer with High-Z Analog Input Protection数据手册Renesas规格书

描述 Description

The HS-1840RH/883S is a radiation hardened, monolithic 16 channel multiplexer constructed with the Intersil Linear Dielectric Isolation CMOS 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 rails during powered operation. Excellent for use in redundant applications, since the secondary device can be operated in a standby unpowered mode affording no additional power drain. More significantly, a very high impedance exists between the active and inactive devices preventing any interaction. One of sixteen channel selection is controlled by a 4-bit binary address plus an Enable-Inhibit input which conve niently controls the ON/OFF operation of several multiplexers in a system. All digital inputs have electrostatic discharge protection.
