PI5A121/PI5A122/PI5A124  
Wide Bandwidth Analog Switches  
Features  
Description  
• Single-Supply Operation (+2V to +6V)  
• Rail-to-Rail Analog Signal Dynamic Range  
• Low On-Resistance (6Ω typ. with 5V supply)  
Minimizes Distortion and Error Voltages  
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 rout-  
ing.  
• On-Resistance Flatness, 3Ω typ.  
• Low Charge Injection Reduces Glitch Errors. Q = 4pC typ.  
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.  
• High Speed. t = 10ns typ.  
ON  
• Wide -3dB Bandwidth: 326 MHz (typ.)  
• High-Current Channel Capability: >100mA  
• TTL/CMOS Logic Compatible  
Each switch conducts current equally well in either direction  
when on. When off, they block voltages up to V+.  
• Low Power Consumption (0.5µW typ)  
• Small outline transistor package minimizes board area  
• Packaging (Pb-free & Green available):  
- 5-pin 65-mil wide SOT23 (T) for PI5A121 and PI5A122  
- 6-pin 65-mil wide SOT23 (T) for PI5A124  
These switches are fully specified with +5V, and +3.3V supplies.  
With +5V, they guarantee <10Ω On-Resistance. On-Resistance  
matching between channels is within 2Ω. On-Resistance flatness  
is less than 55Ω over the specified range. These switches also  
guarantee fast switching speeds (t <20ns).  
ON  
- 5-pin 50-mil wide SC70 (C) for PI5A121/PI5A122  
These products are available in 5-pin SC70 and/or 6-pin SOT23  
plastic packages for operation over the industrial (-40 C to +85 C)  
temperature range.
