U74CBT3251
1-OF-8 FET MULTIPLEXER/
DEMULTIPLEXER
CMOS IC
DESCRIPTION
The U74CBT3251 is a 1-OF-8 high-speed TTL-compatible FET
multiplexer / demultiplexer. The low on-state resistance of the
switch allows connections to be made with minimal propagation
delay.
When output enable (OE) is low, the U74CBT3251 is enabled.
S0, S1, and S2 select one of the B outputs 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)

Note: 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).
