PI5A123
SOTINYTM Low Voltage SPDT Analog Switch
2:1 Mux/Demux Bus Switch
Features
Description
• CMOS Technology for Bus and Analog Applications
The PI5A123 is a low R , fast single-pole double-throw
ON
(SPDT) CMOS switch. It can be used as an analog switch or
as a low-delay bus switch. Specified over a wide operating
power supply voltage range, 1.65V to 5.5V, the PI5A123 has a
maximum ON resistance of 2-Ohms.
• Low ON Resistance: 0.8-ohm at V = 4.5V
DD
• Wide V Range: 1.65V to 5.5V
DD
• Rail-to-Rail Signal Range
• Control Input Over voltage Tolerance: 5.5V min.
• Fast Transition Speed: 5.2ns max. at 5V
• High Off Isolation: -62dB at 1MHz
Break-before-make switching prevents both switches being
enabled simultaneously. This eliminates signal disruption during
switching.
• -70dB (1MHz) Crosstalk Rejection Reduces Signal Distortion
• Break-Before-Make Switching
The control input, IN, tolerates input drive signals up to 5.5V,
independent of supply voltage.
• High Bandwidth: 55 MHz
PI5A123 is an improved direct replacement for the NLAS5123.
• Extended Industrial Temperature Range: –40°C to 85°C
• Improved Direct Replacement for NLAS5123
• Packaging (Pb-free & Green available):
- 6-pin TDFN (1.2mm x 1.0mm)

Notes:
1. 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.
2. The input and output negative voltage ratings may be exceeded if the input and output diode current ratings are observed.
3. Control input must be held HIGH or LOW; it must not float.

Notes:
2. Measured by the voltage drop between NC/NO and COM pins as the indicated current through the switch. On Resistance is determined by the lower
of the voltages on the two (NO, NC, COM).
3. Parameter is characterized but not tested in production.
4. ΔRON = RON max – RON min measured at identical VDD, temperature and voltage levels.
5. Flatness is defined as the difference between the maximum and minimum value of On Resistance over the specified range of conditions.
6. Guaranteed by design
7. The parameter is guaranteed by design but not tested.

Notes:
1. Guaranteed by design
2. The parameter is guaranteed by design but not tested. The bus switch contributes no propagation delay other than the RC delay of the On Re-
sistance of the switch and the 50 pF load capacitance, when driven by and ideal voltage source (zero output impedance).
3. Off Isolation = 20 log10 [VCOM/VNO,NC].
