Q = 4pC typ. • High Speed. tON = 10ns typ. • Wide -3dB Bandwidth: 326 MHz (typ.) • High-Current Channel Capability: >100mA • TTL/CMOS Logic Compatible • 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 - 5-pin 50-mil wide SC70 (C) for PI5A121/PI5A122 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 <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 (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.
