Product Description

The PI5A100 is an improved Quad Single-pole double-throw (4SPDT) CMOS analog switch designed to operate with a single +2V to +6V power supply. The EN pin may be used to place all switches in a high-impedance state. This high precision device is ideal for low-distortion audio, video, and data switching and routing. Each switch conducts current equally well in either direction when on. In the off state each switch blocks voltages up to the power-supply rails. The PI5A100 is fully specified with +5V, and +3.3V supplies. With +5V, it guarantees less than 10Ω On-Resistance. On-Resistance matching between channels is within 2Ω. On-Resistance flatness is less than 4Ω over the specified range. The PI5A100 guarantees fast switching speeds (tON < 12ns). The PI5A100 is available in the narrow-body SOIC and QSOP packages for operation over the industrial (-40°C to +85°C) temperature range.
