DUAL 1-OF-4 FET
MULTIPLEXER/EMULTIPLEXER
DESCRIPTION
The U74CBT3253 is a dual 1-of-4 high-speed TTL-compatible
FET multiplexer/demultiplexer. The low on-state resistance of the
switch allows connections to be made with minimal propagation
delay.
1 OE , 2 OE , S0, and S1 select the appropriate B output for the
A-input data.
FEATURES
* VCC Operating Range From 4V to 5.5V
* Bidirectional Data Flow, With minimal Propagation Delay
* Low ON-State Resistance (RON) Characteristics (RON =5Ω Typ.)
* Low Power Consumption ICC =3μA (Max)

Notes: 1. Absolute maximum ratings are those values beyond which the device could be permanently damaged.
Absolute maximum ratings are stress ratings only and functional device operation is not implied.
2. All voltages are with respect to ground
3. The input and output voltage ratings may be exceeded if the input and output clamp-current ratings are
observed.
