U74CBT3253
DUAL 1-OF-4 FET
MULTIPLEXER/EMULTIPLEXER
CMOS IC
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. CL includes probe and jig capacitance.
2. All input pulses are supplied by generators having the following characteristics: PRR≤10MHz,
ZO=50Ω, tr≤2.5ns, tf≤2.5 ns.
3. The outputs are measured one at a time with one transition per measurement.
4. tPLZ and tPHZ are the same as tdis.
5. tPZL and tPZH are the same as ten.
6. tPLH and tPHL are the same as tpd(s).
7. All parameters and waveforms are not applicable to all devices.
