Overview
UNISONIC TECHNOLOGIES CO.
, LTD U74CBT3257 4-BIT 1-OF-2 FET MULTIPLEXER/ DEMULTIPLEXER CMOS IC  DESCRIPTION The U74CBT3257 is a 4-bit 1-of-2 high-speed TTL-compatible FET multiplexer/demultiplexer.
The low on-state resistance of the switch allows connections to be made with minimal propagation delay.
Output-enable ( OE ) and select-control (S) inputs select the appropriate B1 and B2 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)  ORDERING INFORMATION Ordering Number U74CBT3257G-R16-R U74CBT3257G-P16-R Package SSOP-16 TSSOP-16 Packing Tape Reel Tape Reel  MARKING SSOP-16 TSSOP-16 www.

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 ...
