Product Overview
The MUX508 is a Texas Instruments Signal_Chain device described as an 8-channel analog multiplexer. Its multiplexer configuration is 8:1 single-ended, allowing one of eight source channels to be connected through the device signal path under address and enable control.
Electrical parameters from the manufacturer datasheet include 125 ohm on resistance, 9.4 pF on capacitance, 10 pA input leakage, 0.3 pC charge injection, 92 ns transition time, and 45 uA supply current. The device uses break-before-make switching, and its logic input range is specified from 2 V to VDD.
Supply operation is specified for dual supplies from +/-5 V to +/-18 V and single supplies from 10 V to 36 V. Recommended operating conditions list source, drain, enable, and address pin voltages from VSS to VDD, channel current from -25 mA to 25 mA at TA = 25 °C, and operating temperature from -40 °C to 125 °C.
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.
