The HS-508ARH is a dielectrically isolated, radiation hardened, CMOS analog multiplexer with overvoltage protection. It can withstand analog input voltages much greater than the supplies, eliminating the possibility of damage when supplies are off but input signals are present. It can also withstand brief input transient spikes of several hundred volts without the need for complex external protection networks. The device has higher ON resistance compared to similar unprotected devices, but very low leakage current, resulting in low errors.
The HS-508ARH is a dielectrically isolated, radiation‑hardened CMOS analog multiplexer that can tolerate analog input voltages up to 10 V greater than the supply rails, protecting the device even when supplies are off. It offers break‑before‑make switching, DTL/TTL and CMOS compatibility, and a fast access time.
The datasheet provides electrical specifications, pinout configurations for the 16‑lead side‑braze DIP (HS1‑508ARH) and flat‑pack (HS9‑508ARH) packages, functional and schematic diagrams, and die‑level characteristics. It also lists ordering information and compliance with MIL‑PRF‑38535 requirements.
