Description
Single-SupplyOperation(+2Vto+6V)
Rail-to-RailAnalogSignalRange
The PI5A391A/392A/393A are monolithic analog switches de-
signed for low-voltage, single-supply operation. These high-preci-
sion devices are ideal for low-distortion audio, video, signal
switching and routing applications.

The PI5A391A is a quad single-pole single-throw (SPST), nor-
mally closed (NC) switch. The PI5A392A has four normally open
(NO) switches. The PI5A393A has two NC and two NO switches
per package.

Wide-3dBBandwidth: >200MHz
Each switch conducts current equally well in either direction when
on. When off they block voltages up to the power-supply rails.
High-CurrentChannelCapability:>100mA
TTL/CMOSLogicCompatible
The PI5A391A/392A/393A are fully specified with +5V, and
+3.3V supplies. With +5V, they guarantee <12ohm on-resistance.
On-resistance matching between channels is within 2ohm.
On-resistance flatness is less than 4ohm over the full signal range.
