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), normally open (NO) switch. The PI5A383 is a dual single-pole
double-throw (SPDT) switch. The PI5A385 is a dual doublepole 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. Onresistance matching between channels is within 2Ω. Onresistance flatness is less than 4Ω over the specified range. The
PI5A38X family guarantees fast switching speeds (tON < 15ns).
These products are available in the 16-pin narrow-body SOIC,
QSOP, and PDIP packages for operation over the industrial
(-40oC to +85 oC) temperature range.

Notes:
1. The algebraic convention, where the most negative value is a minimum and the most positive is a maximum, is used in this data sheet.
2. Typical values are for DESIGN AID ONLY, not guaranteed or subject to production testing.
3. Guaranteed by design.
4. ∆RΟΝ = RΟΝ max - RΟΝ min.
5. Flatness is defined as the difference between the maximum and minimum value of on-resistance measured.
6. Leakage parameters are 100% tested at maximum rated hot temperature and guaranteed by correlation at +25ºC.
7. Off Isolation = 20log10 [VCOM/ (VNO or VNC)]. See figure 3.
8. Between any two switches. See figure 4.
9. D = RFLAT(ON)/RL.
