Description

The SV73257A is an ultra-low Ron, low-power, high-

bandwidth, high-speed CMOS/TTL-compatible Quad 2:1

multiplexer/demultiplexer bus switch. It is pin compatible

with industry standard 74F/FCT/LS/AS/ALS257 logic

devices. Its control inputs were not just designed to meet

standard and LV CMOS/TTL logic level, but also

designed to be used with most advanced chipset or SOC

with 1.8V control inputs and outputs. It built in undershoot

clamping diodes on all control inputs and switch inputs

that results in robust and reliable switching.

Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a

stress rating only; functional operation of the device at these or any other conditions above those indicated in the

operational section of this specification is not implied. Exposure to absolute maximum rating conditions for extended

periods may affect

device reliability.

Caution

This integrated circuit can be damaged by ESD if you don’t pay attention to ESD protection. SAVITECH recommends

that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and

installation procedures can cause damage.

ESD damage can range from subtle performance degradation to complete device failure. Precision integrated

circuits

small parametric changes could cause the device not to meet its

may be more susceptible to damage because very

2. V_DD= 3.0 - 4.4V, TA = 25°C ambient and maximum loading.

3. Measured by the voltage drop between I_nand Y_npin at indicated current through the Switch On-Resistance is determined

by the lower of the voltages on the two (I_n, Y_n) pins.

Notes:

1. For max. or min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device type.

2. Guaranteed by design.

3. The switch contributes no propagation delay other than the RC delay of the On-Resistance of the switch and the load

capacitance. The time constant for the switch alone is of the order of 0.25ns for 50pF load. Since this time constant is

much smaller than the rise/fall times of typical driving signals, it adds very little propagation delay to the system.

Propagation delay of the switch when used in a system is determined by the driving circuit on the driving side of the switch

and its interactions with the load on the driven side.
