Description
PI5A4594A/PI5A4596A are single-pole/single-throw (SPST) ana-
log switches that operate from a single +2.0V to +5.5V supply. The
PI5A4594A/PI5A4596A switches are normally open (NO), and the
PI5A4595A/PI5A4597A are normally closed (NC). The PI5A4596A/
PI5A4597A pinouts are optimized for the highest SC70 package
off-isolation available.
These switches have 10-ohm max On-Resistance (R
ON
), with 1.5-
ohms max R
ON
flatness over the analog signal range when powered
from a +5V supply. Leakage currents are 0.5nA and fast switching
times are less than 40ns. They are packaged in a compact 5-pin
SC70 package.

Note
1. Voltages exceeding V+ or GND on any signal terminal are clamped by internal diodes. Limit forward-diode current to maximum current rating.
Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress
ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational
sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device
reliability.

Notes:
2. Parameters are 100% tested at +25C only, and guaranteed by correlation at the full-rated temperature.
3. Algebraic convention is used in this data sheet; the most negative value is shown in the minimum column.
4. Flatness: the difference between maximum & minimum values of ON-resistance measured over specified analog signal ranges.
5. Guaranteed by design.

Applications Information
Analog Signal Levels
Analog signals can range over the supply voltage (V+ to GND) with ON-resistance changing very little over the entire range. The
PI5A4594API5A4597A are bidirectional, so the NO, NC, and COM pins can be used either as inputs or outputs.
