Features
Description
• Low On-Resistance (33ohm typ) Minimizes Distortion and
Error Voltages
• Low Glitching Reduces Step Errors in Sample-and-Holds.
Charge Injection, 2pC typ
• Single-Supply Operation (+2.5V to +16V)
• Improved Second Sources for MAX4501/MAX4502
• On-Resistance Matching Between Channels, <2ohm
• On-Resistance Flatness, <6ohm max
• Low Off-Channel Leakage, <5nA @ +85oC
• TTL/CMOS Logic Compatible
• Fast Switching Speed, tON < 150ns
• Guaranteed Break-Before-Make action (PS303 only)
eliminates momentary crosstalk
• Rail-to-Rail Analog Signal Dynamic Range
• Low Power Consumption, <5µW
• MSOP Package minimizes board area
The PS301/PS302/PS303 are improved high precision, medium
voltage analog switches designed to operate with single power
supplies. The PS301 is a single-pole single-throw (SPST), normally open (NO) switch. The PS302 has the same pinout as the
PS301 but is a normally closed (NC) switch. The PS303 has one
normally open (NO) and one normally closed (NC) switch per
package. Each switch conducts current equally well in either
direction when on. In the off state each switch blocks voltages up
to the power-supply rail.
With a +5V power supply, the PS301/PS302/PS303 guarantee
<60ohm ON-resistance. ON-resistance matching between channels is within 2ohm. ON-resistance flatness is less than 6ohm over
the specified range. All three devices guarantee low leakage
currents (<100pA @ 25oC, <10nA @ +85oC) and fast switching
speeds (tON < 150ns). Break-before-make switching action protects against momentary crosstalk (PS303).
For single-supply operation below 5V, the PI5A317/318/319
are also recommended.

Positive Supply
Overvoltage Protection
Proper power-supply sequencing is recommended for all CMOS
devices. Do not exceed the absolute maximum ratings, because
stresses beyond the listed ratings may cause permanent damage to
the devices. Always sequence V+ on first, and then logic inputs.
If power-supply sequencing is not possible, add two small signal
diodes or two current limiting resistors in series with the supply
pins for overvoltage protection (Figure 1). Adding diodes reduces
the analog signal range, but low switch resistance and low leakage
characteristics are unaffected.

Logic Levels
When powered from +5V the PS301/PS302/PS303 can be operated with either TTL- or CMOS-Logic levels. If V+ is different
than +5V, the logic threshold level will vary.

Power consumption is minimal when the logic control voltages
reach V+ or GND.

Figure 1. Overvoltage protection is accomplished by using two
external blocking diodes or two current limiting resistors.
