Description
The PI5A126/PI5A127 are dual SPST (single-pole single-throw) analog switches designed for single supply operation. These high-precision devices are ideal for low-distortion audio, video, signal switching and routing. The PI5A126 is a normally open (NO) switch. The switch is open when IN is LOW. The PI5A127 is a 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 -ohm ON-resistance. On-resistance matching between channels is within 2 ohms. On-resistance flatness is less than 5 ohms over the specified range. These switches also guarantee fast switching speeds (tON < 20ns). These products are available in 8-pin SOIC and MSOP plastic packages for operation over the industrial temperature range (-40oC to +85oC).
Applications

Notes: 1. The algebraic convention, where the most negative value is a minimum and the 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.
