These high-precision devices are ideal f low-disttion audio, video signal switching and routing. The PA3 is a dual single-pole single-throw (SPST), nmally open (NO) switch. The PA33 is a dual single-pole double-throw (SPDT) switch. The PA3 is a dual doublepole single-throw (DPST), nmally open (NO) function. Each switch conducts current equally well in either direction when on. When off they block voltages up to the power-supply rails. The PA3/33/3 are fully specified with, and +3.3 supplies. With, they guarantee <Ω on-resistance. Onresistance matching between channels is within 2Ω. Onresistance flatness is less than Ω over the specified range. The PA3X family guarantees fast switching speeds (t < ns). These products are available in the 6-pin narrow-body SO, QSOP, and PDP packages f operation over the industrial (- o to + o ) temperature range.
