Data Sheet

1 General Description

The AS1751/AS1752/AS1753 are high-speed, low -vo lt-

age, quad single-pole/single-throw (SPST) analog

switches.

Fast switching speeds, low ON-resistance, and low

power consumption make these devices ideal for single-

cell battery powered applications.

These highly-reliable devices operate from a single +1.6

to +3.6V supply, and are differentiated by the type and

number of switches:

! AS1751 – Four normally open (NO) switches

! AS1752 – Four normally closed (NC) switches

! AS1753 – Two NO switches and Two NC switches

The AS1753 supports break-before-make switching.

With very low ON-resistance (RON), RON matching and

RON flatness, the devices can accurately switch signals

for sample and hold circuits, digital filters, and op-amp

gain switching networks.

The AS1751/AS1752/AS1753 digital logic input is 1.8V

CMOS-compatible when using a +3V supply, and all

devices can handle Rail-to-Rail signals.

The devices are available in a 3mm x 3mm 16-pin TQFN

package and a 14-pin TSSOP package.

Data Sheet - Detailed 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 switchin g 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 (0.9Ω, max) ON-resistance allows high-speed, continuous signals to be

switched in a variety of applicat ions.

Bi-Directional Switching

Pins NOx, NCx, and COMx are bi-directional, thu s 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.

Data Sheet - Application Information

9 Application Information

Power Supply Sequencing

Proper power-supply sequencing is critical for proper switch operation. The power supplies should be started up in the

following sequence:

1. V+

2. NOx, NCx, COMx

Note: Do not exceed the absolute maximum ratings (see page 2).

Overvoltage Protection

ON-resistance increases slightly at lower supply voltages.

Figure 12. Overvoltage Protection using 2 External Blocking Diodes

Adding diode D2 to the circuit shown in Figure 12 causes the logi c threshold to be shifted relative to GND. Diodes D1

and D2 also protect against ove r voltage conditions.

For example, in the circuit shown in Figure 12, if the supply voltage goes below the absolute maximum rating, and if a

fault voltage up to the absolute maximum rating is applied to an analog signal pin, no damage will result.

Power Supply Bypass

Power supply connections to the devices must maintain a low impedance to ground. This can be done using a bypass

capacitor, which will also improve noise margin and prevent switching noise propagation from the V+ supply to other

components.

A 0.1µF bypass capacitor, connected from V+ to GND (see Figure 18 on page 11), is adequate for most applications.

Logic Inputs

Driving INx Rail-to-Rail will help minimize po wer consumption.

Layout Considerations

High-speed switches require proper layout and design procedures for optimum performance.

! Short, wide traces should be used to reduce stray inductance and capacitance.

! Bypass capacitors should be as close to the device as possible.

! Large ground planes should be used wherever possible.

9. All variations may be constructed per Figure 19, however variations may alternately be constructed between square

or rectangle shape per dimensions D and E.

10. Refer to the Dimensions Table for a complete set of dimensions.

11. Bilateral coplanarity zone applies to the exposed heat sink slug as well as the terminals.

12. Depending on the method of lead termination at the edge of the package, pullback (L1) may be present. L minus

L1 to be ≥ 0.33mm.

13. For variations with more than one lead count for a given body size and terminal pitch, each lead count for that vari-

ation is denoted by a dash number (e.g., -1 or -2).

14. NJR designates non-JEDEC registered package.

Figure 20. 14-pin TSSOP Package

Notes:

1. All dimensions are in millimeters; angles in degrees.

2. Dimensions and tolerancing per ASME Y14.5M-1994.

3. Dimension D does not include mold flash, protrusions, or gate burrs. Mold flash, protrusions, or gate burrs shall not

exceed 0.15mm per side.

4. Dimension E1 does not include interle ad flash or protrusion. Interlead flash or protrusion shall not exceed 0.25mm

per side.

5. Dimension b does not include damba r pro trusion. Allowable dambar protrusion shall be 0.08mm total in excess of

dimension b at maximum material condition. Dambar cannot be located on the lower radius of th e foot. Minimum

space between protrusion and adjacent lead is 0.07mm for 0.5mm pitch packages.

6. Terminal numbers shown are for reference only.

7. Datums A and B to be determined at dat um plane H.

8. Dimensions D and E1 to be determi ned at datum plane H.

9. This dimension applies only to variations with an even number of leads per side. For variations with an odd number

of leads per package, the center lead must be coincident with the package centerlin e, datum A.

10. Cross section A-A to be determined at 0.10 to 0.25mm from the leadtip.
