Product Overview
TMUX1072 is a Texas Instruments Signal_Chain 2-channel 2:1 analog multiplexer. The device supports a recommended 2.3 to 5.5 V supply range, with COM1 and COM2 recommended for 0 to 18 V input/output operation and NC/NO pins recommended for 0 to 5.5 V operation. Absolute maximum ratings include -0.5 to 20 V on COM inputs/outputs and -0.5 to 6 V on NC/NO, digital input, and FLT output pins.
Switch performance is defined by 6 Ω typical on-state resistance, 0.07 Ω typical channel matching, 2.5 Ω typical flatness, and 1.2 GHz typical bandwidth into a 50 Ω load. Dynamic parameters include 130 ps typical propagation delay, 9 ps typical skew of opposite transitions, and 0.9 µs minimum to 1 µs maximum switching time between channels.
The device is available in UQFN-12 2.00 mm x 1.70 mm and VSSOP-10 3.00 mm x 5.00 mm packages. It includes overvoltage protection detection, FLT output behavior, undervoltage lockout, and overtemperature detection, supporting compact signal-chain routing where voltage limits, bandwidth, and temperature range are design constraints.
