A product Line of Pb Diodes Incorporated Lead-free Green PS508/PS509 Precision 8-Channels, Differential 4-Channels, 36V Analog Multiplexers Features Description Low On-Capacitance e PTh S508 and PS509 are modern, complementary metal-oxide semiconductor (CMOS), analog multiplexers (muxes). The PS508 PS508: 30pF offers 8:1 single-ended channels, whereas the PS509 offers dif - PS509: 20pF ferential 4:1 or dual 4:1 single-ended channels. e Th PS508 and Low Input Leakage: 30pA PS509 work equally well with either dual supplies (5V to 18V) Low Charge Injection: 0.9pC or a single supply (10 V to 36 V). eTh y also perform well with symmetric supplies (such as VDD = 12V, VSS = 12V), and un- Rail-to-Rail Operation symmetric supplies (such as VDD = 12V, VSS = 5V). All digital Wide Supply Range: 5V to 18V, 10V to 36V inputs have TTL-logic compatible thresholds, ensuring both TTL Low On-Resistance: 125 and CMOS logic compatibility when operating in the valid sup- Transition Time: 171ns ply voltage range. Break-Before-Make Switching Action e PTh S508 and PS509 have very low on and off leakage currents, EN Pin Connectable to VDD allowing these multiplexers to switch signals from high input im- Logic Levels: 2V to VDD pedance sources with minimal error. A low supply current of 135 A allows for use in portable applications. Low Supply Current: 135A ESD Protection HBM: 2000V Applications Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2) Factory Automation and Industrial Process Controls Halogen and Antimony Free.
