The TMUX1104 is a precision complementary metal-oxide semiconductor (CMOS) multiplexer (MUX). The TMUX1104 offers a single channel, 4:1 configuration. A wide operating supply of 1.08V to 5.5V makes this device an excellent choice for a broad array of applications from medical equipment to industrial systems. The device supports bidirectional analog and digital signals on the source (Sx) and drain (D) pins ranging from GND to VDD. All logic inputs have 1.8V logic compatible thresholds, allowing for both TTL and CMOS logic compatibility when operating in the valid supply voltage range. Fail-Safe Logic circuitry allows voltages on the control pins to be applied before the supply pin, protecting the device from potential damage.
The TMUX1104 is part of the precision switches and multiplexers family of devices. These devices have very low on and off leakage currents and low charge injection, allowing them to be used in high precision measurement applications. A low supply current of 5nA and small package options enable use in portable applications.

PIN | TYPE(1) | DESCRIPTION | |
---|---|---|---|
NAME | NO. | ||
A0 | 1 | I | Address line 0. Controls the switch configuration as shown in Table 7-1. |
S1 | 2 | I/O | Source pin 1. Can be an input or output. |
GND | 3 | P | Ground (0V) reference |
S3 | 4 | I/O | Source pin 3. Can be an input or output. |
EN | 5 | I | Active high logic enable. When this pin is low, all switches are turned off. When this pin is high, the A[1:0] logic inputs determine which switch is turned on. |
VDD | 6 | P | Positive power supply. This pin is the most positive power-supply potential. For reliable operation, connect a decoupling capacitor ranging from 0.1µF to 10µF between VDD and GND. |
S4 | 7 | I/O | Source pin 4. Can be an input or output. |
D | 8 | I/O | Drain pin. Can be an input or output. |
S2 | 9 | I/O | Source pin 2. Can be an input or output. |
A1 | 10 | I | Address line 1. Controls the switch configuration as shown in Table 7-1. |
