PI5A100
Precision, Wide-Bandwidth
Quad SPDT Analog Switch
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 10 On-Resistance. On-Resistance
matching between channels is within 2. On-Resistance flatness
is less than 4 over the specified range. The PI5A100 guarantees
fast switching speeds (t
ON
< 12ns).
The PI5A100 is available in the narrow-body SOIC and QSOP
packages for operation over the industrial (-40C to +85C) tem-
perature range.

Applications Information
Overvoltage Protection
Proper power-supply sequencing is recommended for all CMOS
devices. Do not exceed the absolute maximum ratings, because
stresses beyond the listed ratings may cause permanent damage
to the devices. Always sequence V+ on first, followed by V-, and
then logic inputs. If power-supply sequencing is not possible, add
two small signal diodes or two current limiting resistors in series
with the supply pins for overvoltage protection (Figure 8). Adding
diodes reduces the analog signal range, but low switch resistance
and low leakage characteristics are unaffected.
RGB Switch
Figure 9 illustrates a simple low cost RGB switch. The RGB -
to-Composite Decoder produces either NTSC or S-VHS video
from an RGB source. Asingle PI5A100 selects one of the two
video sources to produce either SVHS, Composite or RGB video
outputs. The low insertion loss of the PI5A100 eliminates the need
for expensive input/output buffers.
Figure 8: Overvoltage protection is accomplished using two ex-
ternal blocking diodes or two current limiting resistors.
Figure 9: The single PI5A100 is used to select SVHS, VGA or Composite video outputs.

Applications
Audio Muting Function
Figure 8 shows the PI5A100 in an audio card muting application.
The original problem was one of excessive popping/clicking noise
appearing when connecting disconnecting external loads, and at
power on/off. The PI5A100 performs a muting function by grounding
the outputs at power on/off and during the transition time. The
32 headset impedance demands a very low and very flat switch-
on resistance to reduce THD and signal loss.
Figure 10: The PI5A100 momentarily mutes the stereo outputs by connecting them to ground during transition times.
Paralleling two sections of the PI5A100 produces a Ron of 2.5
with an unsurpassed
0.5 flatness.
To handle AC signals it was necessary to power the device with
3V provided by two Zener diodes: Z1 and Z2. The select and
Enable control signals are shifted by using twpo 2.5V Zener diodes
Z3,Z4 and pull down resistors connected to -3V.
