Q = 1.6pC typ. • High Speed. tON = 7ns typ. • Wide –3dB Bandwidth: 326 MHz • High-Current Channel Capability: >100mA • TTL/CMOS Logic Compatible • Low Power Consumption (5μW typ.) • Packaging (Pb-free & Green Available) — 8-pin, 118 mil plastic MSOP (U) The PI5A127 is a 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 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-ohm. On-resistance flatness is less than 5-ohm 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).
