The TMUX9832 is a 32-channel low harmonic distortion, low resistance, low capacitance high-voltage analog switch integrated circuit (IC) with latch-up immunity. Each device has 32 independently selectable 1:1, single-pole, single-throw (SPST) switch channels. The device only requires a +5 V supply, while still being able to support ±110 V analog signals. TMUX9832 also integrates bleed resistors on its drain (Dx) pins to discharge capacitive loads, like piezoelectric transducers. TMUX9832 is designed for medical ultrasound imaging and other piezoelectric transducer driver applications.
TMUX9832 integrates cascadable 32-bit shift register with latches for controlling each of the 32 switches. The daisy chain capability allows for many TMUX9832 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 32-bit shift register can operate off of a 1.8 V – 5 V power supply and support clock speeds up to 100 MHz.
