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 <10Ω on-resistance. On-
resistance matching between channels is within 2Ω. On-
resistance flatness is less than 4Ω 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.
