Product Overview
TMUX1511 is a Texas Instruments Signal_Chain device described as a 4-channel SPST analog switch. Its switch configuration is 1:1 SPST with four independently controlled channels, allowing each signal path to be controlled through SEL1, SEL2, SEL3, and SEL4 logic inputs.
The recommended supply voltage range is 1.5 to 5.5 V, while source or drain signal path voltage is specified from 0 to VDD x 2 V with a 5.5 V maximum input/output voltage. When VDD is below 1.5 V, powered-off signal path voltage is specified from 0 to 3.6 V. Logic control input voltage is 0 to 5.5 V, with 1.2 V minimum input-high and 0.45 V maximum input-low thresholds.
Electrical characteristics include typ 2 ohm and max 4.5 ohm on-resistance, 3 GHz bandwidth into 50 ohm while on, typ 37 uA supply current, typ 3.3 pF on-capacitance, typ 2.5 pF off-capacitance, 2 pC charge injection, and -0.12 dB insertion loss at 1 MHz. Package options include TSSOP-14, QFN-16, and X2QFN-12; the datasheet also recommends 0.1 uF to 10 uF decoupling between VDD and GND.
