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, singlethrow
(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.
