Description

The PI5A381/383/385A are dual monolithic analog switches designed for single-supply operation. These high-precision devices are ideal for low-distortion audio, video signal switching and routing. The PI5A381 is a dual single-pole single-throw (SPST), nor- mally open (NO) switch. The PI5A383 is a dual single-pole double-throw (SPDT) switch. The PI5A385 is a dual double- pole single-throw (DPST), normally 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 PI5A381/383/385 are fully specified with +5V, and +3.3V supplies. With +5V, they guarantee <10W on-resistance. On- resistance matching between channels is within 2W . On- resistance flatness is less than 4W over the specified range. The PI5A38X family guarantees fast switching speeds (t ON < 15ns). These products are available in the 16-pin narrow-body SOIC, QSOP, and PDIP packages for operation over the industrial (-40 oC to +85 oC) temperature range.
