Device Overview
TMUX1112PWR implements four independently controlled active-high SPST analog switches. Its very low leakage and low charge injection make it more suitable for precision signal routing than for load switching or power-distribution use.

Engineering Selection Guidance
TMUX1112PWR is suited to precision analog routing where leakage and charge injection can dominate error. The ±3 pA on-leakage figure is a 25 °C typical value at VDD = 5 V and VD = VS = 2.5 V, not a full-temperature maximum; TI specifies up to ±0.95 nA over -40 °C to 125 °C under that signal condition. Likewise, 2 Ω on-resistance is a 25 °C typical value. Check source impedance, signal swing, switch on-resistance variation and off-isolation/crosstalk requirements for the actual acquisition or control path.
Procurement Notes
Texas Instruments lists the exact orderable TMUX1112PWR as ACTIVE. The verified manufacturer package is TSSOP-16 (PW). Confirm commercial availability, lot/date-code requirements and final terms through the RFQ process.
