Product Overview
TMUX1204DGSR is a 4:1 single-channel CMOS analog multiplexer with a bidirectional signal path. Its 1.08 V to 5.5 V single-supply range and 1.8 V-compatible control inputs let the signal path and digital control interface be evaluated separately.
TI lists 125 MHz bandwidth, 10 nA typical supply current and 14 ns transition time. These specifications address bandwidth, static power and switching timing respectively; they are not interchangeable measures of signal accuracy.

Selection Notes
Break-before-make behavior reduces momentary channel overlap during selection changes; it does not describe analog settling accuracy.
The 0.75 µA on-state leakage figure is a maximum parametric value and should remain separate from the 10 nA typical supply-current figure.
Fail-safe logic applies to the control-input behavior and must not be described as overvoltage protection for the analog signal path.
DGSR is the 2500-unit large-reel VSSOP-10 orderable, rated from -40 to +125 °C.
Lifecycle and Procurement Context
Texas Instruments lifecycle status for this exact orderable is Active Production. Lifecycle status is included for procurement planning and does not imply HKEQGOO stock, lead time or delivery availability.
