The HI-506/HI-507 and HI-508/HI-509 are single 16-channel and 8-channel/differential 8-channel and 4-channel CMOS analog multiplexers. They utilize the Dielectric Isolation (DI) process, which eliminates latchup and offers lower substrate leakage and parasitic capacitance. The switching threshold for each digital input is established by an internal +5V reference, providing a guaranteed minimum of 2.4V for logic '1' and a maximum of 0.8V for logic '0'. It can directly interface with signals from most logic families, such as CMOS, TTL, DTL, and some PMOS, and features transient overvoltage protection.
The HI‑506, HI‑507, HI‑508 and HI‑509 are monolithic CMOS analog multiplexers offering 16‑channel, 8‑channel differential, 8‑channel single‑ended and 4‑channel differential configurations respectively. Each device includes an array of analog switches, a digital decoder for channel selection, internal voltage references for logic thresholds, and an enable input for multiple‑device operation.
The datasheet provides detailed pinouts, functional and schematic diagrams, absolute maximum ratings, electrical specifications, and package dimensions for CERDIP, SOIC and PLCC options. It also lists typical performance parameters such as on‑resistance, access time, power dissipation, and temperature ranges.
