Description

The PI5A121/PI5A122/PI5A124 are analog switches designed
for single-supply operation. These high-precision devices are
ideal for low-distortion audio, video, signal switching and routing.

The PI5A121 is a single-pole throw (SPST) normally open (NO)
switch. The switch is open when IN is LOW. The PI5A122 is
a single-pole single-throw (SPST) normally closed (NC) switch.

Each switch conducts current equally well in either direction
when on. When off, they block voltages up to V+.

These switches are fully specied with +5V, and +3.3V supplies.
With +5V, they guarantee <10Ω On-Resistance. On-Resistance
matching between channels is within 2Ω. On-Resistance atness
is less than 55Ω over the specied range. These switches also
guarantee fast switching speeds (tON <20ns).

These products are available in 5-pin SC70 and/or 6-pin SOT23
plastic packages for operation over the industrial (-40
temperature range.

Notes:

1. The algebraic convention, where most negative value is a minimum and most positive is a maximum, is used in this data sheet.

2. Typical values are for DESIGN AID ONLY, not guaranteed or subject to production testing.

3. Guaranteed by design

4. ΔR

ON = RON

5. Flatness is dened as the difference between the maximum and minimum value of On-Resistance measured.

6. Leakage parameters are 100% tested at maximum rated hot temperature and guaranteed by correlation at +25ºC.

7. Off Isolation = 20log
