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 specified with +5V, and +3.3V supplies. With +5V, they guarantee <10 On-Resistance. On-Resistance matching between channels is within 2. On-Resistance flatness is less than 55 over the specified 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 (-40oC to +85oC) 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. RON = RON max - RON min 5. Flatness is defined 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 +25C. 7. Off Isolation = 20log10 [ VCOM / (VNO or VNC) ]. See Figure 3. 8.
