•
Functionally equivalent to QS3253
Ω bi-directional switch connection between two ports
5Ω
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 QSOP and TSSOP packages
The CBTLV3253 is a dual 1-of-4 high-speed multiplexer/demultiplexer.
The low on-state resistance of the switch allows connections to be made with
minimal propagation delay.
The select (S0, S1) input controls the data flow. The multiplexer/
demultiplexer switches are disabled when the output-enable (OE) input is
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
minimum value of the resistor is determined by the current-sinking capability
of the driver.

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.
