Product Overview
The MUX509 is a Texas Instruments precision analog multiplexer in the Signal_Chain category. Its multiplexer configuration supports 4-channel differential operation or dual 4:1 single-ended operation, with the device also described as an 8:2 mux. The EN pin is active high: a low level turns all switches off, while a high level enables the address-selected switch pair.
Electrical parameters include 125 ohm on resistance, 6.7 pF on capacitance, 10 pA input leakage current, 0.3 pC charge injection, 92 ns transition time, and 45 uA supply current. The device operates from dual supplies of +/-5 V to +/-18 V or a single 10 V to 36 V supply, with a recommended supply differential of 10 V to 36 V.
Package options include 16-pin TSSOP (PW), 5.00 mm x 4.40 mm, and 16-pin SOIC (D), 9.90 mm x 3.91 mm. For assembly and supply bypassing, the datasheet recommends 0.1 uF to 10 uF decoupling capacitors between VDD and GND and between VSS and GND.
