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.
