1 Introduction

This user's guide describes the intended use of the TMUX9616QFPEVM evaluation module (EVM). This board allows for the quick prototyping and evaluation of TI’s TMUX9616PT and TMUX9616NPT multiplexers. The TMUX9616 and TMUX9616N are 16-channel low resistance, low capacitance high-voltage analog switch integrated circuits (IC) with latch-up immunity. Each device has 16 independently selectable 1:1, single-pole, singlethrow (SPST) switch channels. The device works with dual supplies up to ±110V. The TMUX9616 includes bleed resistors on the output while the TMUX9616N does not.

TMUX9616 and TMUX9616N 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 sepeate 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.

Figure 1-1 and Figure 1-2 resemble the received EVM, and the TMUX9616QFPEVM kit contains the following items:

1. TMUX9616QFPEVM
2. 1 mini-USB cable

The TMUX9616N can be ordered seperately and placed on the TMUX9616QFPEVM for evalution.
