3 Description

The TMUX9616 is a 16-channel low resistance, low capacitance high-voltage analog switch integrated circuit (IC) with latch-up immunity. Each device has 16 independently selectable 1:1, single-pole, single-throw (SPST) switch channels. The device works well with dual supplies up to ±110 V. Asymmetric supply biasing is also supported within the recommended supply range. The TMUX9616 supports bidirectional analog and digital signals on the source (Sx) and drain (Dx) pins ranging from VSS to VDD. TMUX9616 also integrates bleed resistors on its source (Sx) and drain (Dx) pins to discharge capacitive loads, like piezoelectric transducers. TMUX9616 is an excellent choice for medical ultrasound imaging and other piezoelectric transducer driver applications.

TMUX9616 integrates cascadable 16-bit shift register with latches for controlling each of the 16 switches. The daisy chain capability allows for many TMUX9616 devices to be controlled without requiring a separate chip-select for every device. To reduce noise in the signal path due to potential clock feed-through, the active low latch enable can be held high while data is loaded into the shift registers. The 16-bit shift register can operate off of a 1.8 V – 5 V power supply. The 16-bit shift register can support clock speeds up to 72 MHz.
