Maxim MAX4509ESE

SP4T4:12400 Ом9 В ~ 36 В

Overview

The MAX4508/MAX4509ESE are 8-to-1 and dual 4-to-1 faultprotected multiplexers that are pin compatible with the industry-standard DG508/DG509. The MAX4508/MAX4509ESE 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 beyondthe rails.Both parts offer ±40V overvoltage protection with supplies off and ±25V protection with supplies on. Onresistance is 400Ω max and is matched between channels to 15Ω max. All digital inputs have TTL logic thresholds, ensuring both TTL and CMOS logic compatibility when using a single +12V supply or dual ±15V supplies♦ ±40V Fault Protection with Power Off ±25V Fault Protection with ±15V Supplies♦ Rail-to-Rail Signal Handling♦ No Power-Supply Sequencing Required♦ All Channels Off with Power Off♦ Output Clamped to Appropriate Supply Voltage During Fault Condition♦ 1kΩ Output Clamp Resistance During Overvoltage♦ 400Ω max On-Resistance♦ 20ns Fault-Response Time♦ ±4.5V to ±20V Dual Supplies +9V to +36V Single Supply♦ TTL/CMOS-Compatible Logic Inputs♦ Data-Acquisition Systems♦ Industrial and Process Control♦ Avionics♦ Signal Routing♦ Redundant/Backup Systems
