Product Overview
TMUX1208 is a Texas Instruments 8:1, one-channel single-ended analog multiplexer for bidirectional signal paths. The signal pins support voltages from 0 V to VDD, while the supply operates from 1.08 V to 5.5 V. Logic control inputs EN, A0, A1, and A2 accept 0 V to 5.5 V, with 5 V logic thresholds specified as 1.49 V to 5.5 V for high and 0 V to 0.87 V for low.
At VDD = 5 V, the signal path has 5 Ω typical on-resistance, 0.15 Ω typical channel matching, and 1.5 Ω typical flatness. Dynamic parameters include 14 ns typical transition time between channels, 8 ns typical break-before-make time, 14 ns typical enable turn-on time, and 5 ns typical enable turn-off time.
The device is available in 16-pin TSSOP (PW) and 16-pin QFN (RSV) packages. Thermal resistance is 118.9°C/W for the PW package and 134.6°C/W for the RSV package. The datasheet recommends a 0.1 µF to 10 µF VDD decoupling capacitor between VDD and GND.
