Datasheet
1 General Description
The AS1746 is a low on-resistance (RON), low-voltage,
dual-single-pole/double-throw (SPDT) analog switch
designed to operate from a single +1.8 to +5.5V supply.
The device features a 0.5Ω (max) RON for normally
closed (NC) switches and a 0.6Ω (max) RON for nor-
mally open (NO) switches using a +2.7V supply.
The AS1746 features break-before-make switching
(2ns) with tON = 50ns and tOFF = 30ns (using a +2.7V
supply).
The digital logic inputs are 1.8V logic-compatible with
+2.7 to +3.3V supplies.
The AS1746 is available in a TDFN-10 (3x3mm) pack-
age and a WL-CSP-10 package.

8 Detailed Description
The AS1746 is a low on-resistance, low-voltage, asymmetrical dual-SPDT analog switch designed to operate from a
single +1.8 to +5.5V supply. The device is fully specified for nominal 3V applications and features break-before-make
switching and fast switching speeds (t ON = 60ns max, tOFF = 35ns max).
The device provides 0.5Ω (max) RON for its NC switch, and 0.6Ω (max) RON for its NO switch for applications that
require asymmetrical loads.

9 Application Information
Digital Control Inputs
The AS1746 logic inputs can handle up to +5.5V regard less of the supply voltage. For example, with a +3.3V supply,
INx may be driven low to GND and high to 5.5V. Driving INx rail-to-rail minimizes power consumption.
Analog Signal Levels
Analog signals that range over the entire supply voltage (V+ to GND) are passed with very little change in RON (see
T ypical Operating Characteristics on page 6). The switches ar e bi-directional, s o the NOx, NCx, and COMx pins can be
used as inputs or outputs.
Power Supply Sequencing
Proper power supply sequencing is recommended for all CMOS device s. The recommended sequence is as follows:
1. V+
2. NOx, NCx, COMx
Always apply V+ before applying analog signals, especially if the analog signal is not current limited. If this sequencing
is not possible, and if the analog inputs are not current limited to <20mA, add a small signal protection diode (D1) as
shown in Figure 16.
Overvoltage Protection
Using a protection diode will reduce the analog range to a diode voltage drop (approximately 0.7V) below V+ (for D1).
RON will increase slightly at low supply voltages.
Caution: The maximum supply voltage (V+) must not exceed +7V. Do not exceed the absolute maximum ratings
because stresses beyond the ratings listed in Absolute Maximum Ratings on page 3 may cause permanent
damage to the device.
Note: Protection diode D1 can also protect the device from some overvoltage conditions.
Figure 16. Overvoltage Protections using 2 External Blocking Diodes
Note: No damage will result to the circuit shown in Figure 16 if the supply voltage is below the absolute maximum rat-
ing applied to an analog signal pin (NOx, NCx, or COMx).
