These high-precision devices are ideal for low-distortion audio, video, signal switching and routing applications. The PI5A39A is a quad single-pole single-throw (SPST), normally closed (NC) switch. The PI5A392A has four normally open (NO) switches. Each switch conducts current equally well in either direction when on. When off they block voltages up to the power-supply rails. The PI5A39A/392A are fully specified with +5V, and +3.3V supplies. With +5V, they guarantee <2-ohm on-resistance. On-resistance matching between channels is within 2-ohm. On-resistance flatness is less than 4ohm over the full signal range. The PI5A39X family guarantees fast switching speeds (t < 2ns). These products are available in the 6-pin narrow-body SOIC, and QSOP packages for operation over the industrial (-4 o C to +85 o C) temperature range.
