DESCRIPTION:

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,

minimum value of the resistor is determined by the current-sinking capability

of the driver.

FEATURES:

− Functionally equivalent to QS3253

− 5Ω Switch Connection between Two Ports

− Isolation Under Power-Off Conditions

− Over-voltage tolerant

− Latch-up performance exceeds 100ma

− ESD > 2000V per MIL-STD-883, Method 3015;

> 200V using machine model (C = 200pF, R = 0)

− Available in SSOP, QSOP, and TSSOP packages
