Mingjiada Electronics Supply TI TMUX7208 44V Latch-Up Immune, 8:1 Precision Single Channel Multiplexer

Shenzhen Mingjiada Electronics Co., Ltd. — Long-term supplier of the TI (Texas Instruments) TMUX7208 44V, 8:1 precision multiplexer. Designed for high-voltage analogue signal acquisition, multi-channel signal switching and precision measurement systems, this device features an 8:1 multiplexing architecture, enabling designers to achieve efficient switching and conditioning of multiple signals in industrial control, test and measurement, medical electronics and data acquisition equipment. Mingjiada Electronics offers support for the TMUX7208, including sample procurement, small-batch orders and high-volume supply, assisting customers in confirming packaging, stock availability, lead times and pricing information.

TMUX7208 is an 8:1 single-channel precision multiplexer launched by TI; The TMUX7209 is a 4:1 dual-channel multiplexer featuring low on-resistance and low charge injection. This device operates reliably when powered by a single supply (4.5 V to 44 V), a dual supply (±4.5 V to ±22 V) or an asymmetric supply (e.g. VDD = 12 V, VSS = –5 V). The TMUX720x series supports bidirectional analogue and digital signals in the VSS to VDD range on the source (Sx) and drain (D) pins.

TMUX7208 is a precision switch and multiplexer series featuring extremely low on- and off-state leakage currents, making it suitable for high-precision measurement applications. The TMUX7208 series features latch-up suppression, which prevents high-current faults between parasitic structures within the device, typically caused by overvoltage events. A latch-up condition typically persists until the supply rail is shut down and may result in device failure. Latch-up suppression enables the TMUX7208 series of switches and multiplexers to be used in harsh environments.
