Functionally equivalent to QS3251
5Ω Switch Connection between Two Ports
Isolation Under Power-Off Conditions
Over-voltage tolerant
Latch-up performance exceeds 100ma
VCC = 2.3V - 3.6V, normal range
ESD > 2000V per MIL-STD-883, Method 3015;
> 200V using machine model (C = 200pF, R = 0)
Available in SSOP, QSOP, and TSSOP packages
The select input (S0, S1, S2) controls the data flow. The multiplexer/
demultiplexerswitches aredisabledwhentheoutput-enable(OE)inputis
high.
To ensure that the device is in high-impedance state during power up
or power down, OE should be tied to VCC through a pullup resistor; the
minimumvalueoftheresistorisdeterminedbythecurrent-sinkingcapability
of the driver.

NOTE:
1. Stresses greater than those listed under ABSOLUTE MAXIMUM
RATINGS may cause permanent damage to the device. This is a
stress rating only and functional operation of the device at these or
any other conditions above those indicated in the operational sections
of this specification is not implied. Exposure to absolute maximum
rating conditions for extended periods may affect reliability.

NOTES:
1. Typical values are at VCC = 3.3V, +25°C ambient.
2. The increase in supply current is attributable to each output that is at the specified voltage level rather than VCC or GND.
3. This is measured by the voltage drop between the A and B terminals at the indicated current through the switch. On-state resistance is determined
by the lower of the voltages of the two (A or B) terminals.

NOTE:
1. The propagation delay is the calculated RC time constant of the typical on-state resistance of the switch and the specified load capacitance when
driven by an ideal voltage source (zero output impedance).
