Data Sheet

AS1741, AS1742, AS1743

High-Speed, Low-Voltage, Single-Supply, 0.8Ω,

Dual SPST Analog Switches

1 General Description

2 Key Features

ꢀ ON-Resistance:

- 0.8Ω (+3V supply)

- 2.5Ω (+1.8V supply)

The AS1741/AS1742/AS1743 are high-speed, low-volt-

age, dual 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.

ꢀ RON Matching: 0.08Ω (+3V supply)

ꢀ RON Flatness: 0.18Ω (+3V supply)

ꢀ Supply Voltage Range: +1.6 to +3.6V

ꢀ Switching Action: tON = 22ns, tOFF = 14ns

ꢀ Current-Handling: 250mA Continuous

ꢀ Break-Before-Make Switching (AS1743)

ꢀ Rail-to-Rail Signal Handling

These highly-reliable devices operate from a single +1.6

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

number of switches as listed in Table 1.

Switch Types

Two Normally Open (NO) Switches

Two Normally Closed (NC) Switches

One NO Switch and One NC Switch

The AS1743 supports break-before-make switching.

ꢀ 1.8V CMOS Logic Compatible (+3V supply)

ꢀ Total Harmonic Distortion: 0.03%

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.

ꢀ Operating Temperature Range: -40 to +85ºC

The AS1741/AS1742/AS1743 digital logic input is 1.8V

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

all devices can handle Rail-to-Rail signals.

ꢀ Package Types:

- 8-pin MSOP

- 8-pin SOT23

The devices are available in an 8-pin MSOP package

and an 8-pin SOT23 package.

3 Applications

The devices are ideal for use in power routing systems,

cordless and mobile phones, MP3 players, CD and DVD

players, PDAs, handheld computers, digital cameras,

hard drives, and any other application where high-speed

signal switching is required.
