Description for the TMUX7612

The TMUX7612 is a complementary metal-oxide semiconductor (CMOS) switch device with four independently selectable 1:1, single-pole, single-throw (SPST) switch channels. The device works with a single supply (4.5 V to 50 V), dual supplies (±4.5 V to ±25 V), or asymmetric supplies (such as V DD = 37.5 V, V SS = –12.5 V). The TMUX7612 supports bidirectional analog and digital signals on the source (Sx) and drain (Dx) pins ranging from V SS to V DD.

The switches of the TMUX7612 are controlled with appropriate logic control inputs on the SELx pins. The TMUX7612 features a special architecture which allows for ultra-low charge injection. This feature helps prevent unwanted coupling from the control input to the analog output of the device and reduces AC noise and offset errors.

The TMUX7612 is a part of the precision switches and multiplexers family of devices and have very low on and off leakage currents allowing them to be used in high precision measurement applications.

Carrier options

You can choose different carrier options based on the quantity of parts, including full reel, custom reel, cut tape, tube or tray.

A custom reel is a continuous length of cut tape from one reel to maintain lot- and date-code traceability, built to the exact quantity requested. Following industry standards, a brass shim connects an 18-inch leader and trailer on both sides of the cut tape for direct feeding into automated assembly machines. TI includes a reeling fee for custom reel orders.

Cut tape is a length of tape cut from a reel. TI may fulfill orders using multiple strips of cut tapes or boxes to satisfy the quantity requested.

TI often ships tube or tray devices inside a box or in the tube or tray, depending on inventory availability. We pack all tapes, tubes or sample boxes according to internal electrostatic discharge and moisture-sensitivity-level protection requirements.
