LOW-VOLTAGE DUAL
1-OF-4 MULTIPLEXER/
DEMULTIPLEXER
IDT74CBTLV3253
FEATURES:
DESCRIPTION:
• Functionally equivalent to QS3253
• 5Ω switch connection between two ports
• Isolation under power-off conditions
• Over-voltage tolerant
TheCBTLV3253is adual1-of-4high-speedmultiplexer/demultiplexer.
Thelowon-stateresistanceoftheswitchallowsconnectionstobemadewith
minimalpropagationdelay.
The select (S0, S1) input controls the data flow. The multiplexer/
demultiplexerswitches aredisabledwhentheoutput-enable(OE)inputis
high.
• 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 QSOP and TSSOP packages
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 current 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 driven by an ideal voltage source
(zero output impedance).
