MAX4538 Maxim, MAX4538 Datasheet - Page 7

• Manufacturer Part Number: MAX4538
• Description: The MAX4536/MAX4537/MAX4538 are quad, low-voltage, single-pole/single-throw (SPST) analog switches with a common enable pin
• Manufacturer: Maxim

(V+ = +5V, V- = -5V GND = 0V, T
* NO_/NC_ and COM_ pins are identical and interchangeable. Either may be considered as an input or an output; signals pass equally
well in either direction.

Logic-Control Digital Inputs. Control each switch (see Truth Tables ), except when
EN is high.
Analog Switch Common* Terminals
Analog Switch Normally Open* or Normally Closed* Terminals (see Truth Tables )
Disable Logic Input. Connect logic high to EN to disable (open) all switches.
Ground. Connect to digital ground. (Analog signals have no ground reference;
they are limited to V+ and V-.)
Negative Analog Supply-Voltage Input. Connect V- to GND for single-supply operation.
Positive Analog and Digital Supply-Voltage Input. Internally connected to substrate.
