8-CHANNEL ANALOG
MULTIPLEXER/DEMULTIPLEXER
DESCRIPTION
The U74LVX4051 is a high speed ，low-voltage drive analog
SOP-16
multiplexer/demultiplexer using silicon gate CMOS technology. In 3V
and 5V systems these can achieve high-speed operation with the low
power dissipation that is a feature of CMOS.
The U74LVX4051 offer analog/digital signal selection as well as
mixed signals. The 4051 has an 8-Channel configuration.
The switchses for each channel are turned on by the control pin
digital signals.
TSSOP-16
Although the control signal logical amplitude (VCC-GND) is small,the
device can perform large-amplitude (VCC-VEE) signal switching.
For example, if VCC=3V, GND=0V and VEE=-3V, signals between
-3V and +3V can be switched from the logical circuit using a signal 3V
power supply.
All input pins are equipped with a newly developed input protection
circuit that avoids the need for a diode on the plus side (forword side
from the input to the VCC). As a result, for example, 5V signals can be
permitted on the inputs even when the power supply voltage to the
circuits is off. As a result of this input power protection, the
U74LVX4051 can be used in a variety of applications, including in the
system which has two power supplies, and in battery bachup circuits.
FEATURES
* Low ON resistance: RON=22Ω(Typ.)(VCC-VEE=3V)
ON=15Ω(Typ.)(VCC-VEE=6V)
* Input level: VIL=0.8V(Max.)(VCC=3V)
VIH=2.0V(Min.)(VCC=3V)
*
R
* High Speed: tpd=3ns (Typ.)(VCC=3V)
* Low power Dissipation: ICC=4μA (Max.)(TA=25°C)
* Power down protection is provided on all control inputs
* Pin and function compatible with U74HC4051
