Features, Applications

SOTINYTM Low-Voltage, Single-Supply, 1-Ohm SPST CMOS Analog Switches

1-Ohm max. ON-Resistance 0.15-Ohm max. ON-Resistance Flatness at +25C Fast Switching tON = 50ns max. tOFF = 50ns max. to +5.5V Single-Supply Operation TTL/CMOS-Logic Compatible 57dB Off-Isolation 1MHz 4nA max. Off-Leakage at +25C Package: 5-Pin SOT-23


PI5A4626/PI5A4629, single-pole/single-throw (SPST) analog switches that operate from a single to +5.5V supply, are normally open (NO). The PI5A4629 pinout is optimized for the highest SOT-23 package off-isolation available. These switches have 1-ohm max ON-resistance (RON), with 0.12ohm max RON flatness over the analog signal range when powered from a +5V supply. Leakage currents are 0.5nA and fast switching times are less than 50ns. They are packaged in a compact 5-pin SOT-23 package.

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

Notes: 1. The algebraic convention, where most negative value is a minimum and 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. RON = RON max. - RON 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 +25C. 7. Off Isolation 20log10 [ VCOM / (VNO or VNC) See Figure 3. 8. Between any two switches.
