AS1751/AS1752/AS1753
Data Sheet - Deta iled Description
8 Detailed Description
The AS1751/AS1752/AS1753 are low ON-resistance, low-voltage, quad analog SPST switches that operate from a
single +1.6 to +3.6V supply.
CMOS process technology allows switching of analog signals that are within the supply voltage range (GND to V+).
Figure 11. 16-pin TQFN Block Diagrams
ON-Resistance
When powered from a +3V supply, the low (0.9
Ω, max) ON-resistance allows high-speed, continuous signals to be
switched in a variety of applications.
Bi-Directional Switching
Pins NOx, NCx, and COMx are bi-directional, thus they can be used as inputs to- or outputs from other components.
Analog Signal Levels
Analog signals ranging over the entire supply voltage range (V+ to GND) can be switched with very little change in ON-
resistance (see Typical Operating Characteristics on page 6).
Logic Inputs
The devices’ logic inputs can be driven up to +3.6V regardless of the supply voltage value. For example, with a +1.8V
supply, INx may be driven low to GND and high to +3.6V. This allows the devices to interface with +3V systems using
a supply of less than 3V.
