Description

The PI5A126/PI5A127 are dual SPST (single-pole single-throw)
analog switches designed for single supply operation.
These high-precision devices are ideal for low-distortion audio,
video, signal switching and routing.

The PI5A126 is a normally open (NO) switch. The switch is open
when IN is LOW. The PI5A127 is a normally closed (NC) switch.

Each switch conducts current equally well in either direction
when on. When off, they block voltages up to V+.

These switches are fully specified with +5V and +3.3V supplies.
With +5V, they guarantee <10 -ohm ON-resistance. On-resistance
matching between channels is within 2 ohms. On-resistance flat­ness is less than 5 ohms over the specified range. These switches
also guarantee fast switching speeds (tON < 20ns).

These products are available in 8-pin SOIC and MSOP plastic
packages for operation over the industrial temperature range
(–40oC to +85oC).

Caution: Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating
and operation of the device at these or any other conditions beyond those indicated in the operational sections of this specification is not implied.

Note 1:
Signals on NC, NO, COM, or IN exceeding V+ or GND are
clamped by internal diodes. Limit forward diode current to 30mA.

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.

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 [ V
