Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers

will need to change in order to meet ON Semiconductor’s system requirements. Since the ON Semiconductor

product management systems do not have the ability to manage part nomenclature that utilizes an underscore

(_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain

device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated

device numbers. The most current and up-to-date ordering information can be found at www.onsemi.com. Please

email any questions regarding the system integration to Fairchild_questions@onsemi.com.

FST3253

Dual 4:1 Multiplexer/Demultiplexer Bus Switch

General Description

Features

The Fairchild Switch FST3253 is a dual 4:1 high-speed

CMOS TTL-compatible multiplexer/demultiplexer bus

switch. The low on resistance of the switch allows inputs to

be connected to outputs without adding propagation delay

or generating additional ground bounce noise.

■ 4Ω switch connection between two ports.

■ Minimal propagation delay through the switch.

■ Low l_CC

■ Zero bounce in flow-through mode.

■ Control inputs compatible with TTL level.

When OE is LOW, S₀and S₁connect the A Port to the

selected B Port output. When OE is HIGH, the switch is

OPEN and a high-impedance state exists between the two

ports.

Note 1: The Absolute Maximum Ratings are those values beyond which

the safety of the device cannot be guaranteed. The device should not be

operated at these limits. The parametric values defined in the Electrical

Characteristics tables are not guaranteed at the absolute maximum rating.

The Recommended Operating Conditions tables will define the conditions

for actual device operation.

Note 2: The input and output negative voltage ratings may be exceeded if

the input and output diode current ratings are observed.

Note 3: Unused control inputs must be held HIGH or LOW. They may not

float.
