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.

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. V+ NO COM Vg 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. V- Power consumption is minimal when the logic control voltages reach V+ or GND. GND Figure 1. Overvoltage protection is accomplished by using two external blocking diodes or two current limiting resistors. Ordering Information Te mp.
