MAX4508-MAX4509中文资料美信数据手册PDF规格书

General Description

The MAX4508/MAX4509 are 8-to-1 and dual 4-to-1 fault protected multiplexers that are pin-compatible with the industry-standard DG508/DG509. The MAX4508/MAX4509 operate with dual supplies of ±4.5V to ±20V or a single supply of +9V to +36V. These multiplexers feature fault-protected inputs, Rail-to-Rail® signal handling capability, and overvoltage clamping at 150mV beyond the rails.
