Table 5-1 Pin Functions TMUX4051

PIN		TYPE⁽¹⁾	DESCRIPTION⁽²⁾
NAME	NO.	TYPE⁽¹⁾	DESCRIPTION⁽²⁾
S4	1	I/O	Source pin 4. Signal path can be an input or output.
S6	2	I/O	Source pin 6. Signal path can be an input or output.
D	3	I/O	Drain pin (common). Signal path can be an input or output.
S7	4	I/O	Source pin 7. Signal path can be an input or output.
S5	5	I/O	Source pin 5. Signal path can be an input or output.
EN	6	I	Active low logic enable. When this pin is high, all switches are turned off. Table 8-1 lists how the A[2:0] address inputs determine which switch is turned on when this pin is low.
V_SS	7	P	Negative power supply. This pin is the most negative power-supply potential. For reliable operation, connect a decoupling capacitor ranging from 0.1µF to 10µF between V_SS and GND.
GND	8	P	Ground (0V) reference
A2	9	I	Address line 2. Table 8-1 provides information about how A2 controls the switch configuration.
A1	10	I	Address line 1. Table 8-1 provides information about how A1 controls the switch configuration.
A0	11	I	Address line 0. Table 8-1 provides information about how A0 controls the switch configuration.
S3	12	I/O	Source pin 3. Signal path can be an input or output.
S0	13	I/O	Source pin 0. Signal path can be an input or output.
S1	14	I/O	Source pin 1. Signal path can be an input or output.
S2	15	I/O	Source pin 2. Signal path can be an input or output.
V_DD	16	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 V_DD and GND.
Thermal pad		—	The thermal pad is not connected internally. It is recommended that the pad be left floating or tied to GND.

(1) I = input, O = output, I/O = input and output, P = power.
