DESCRIPTION
The 74LVQ158 is a low voltage CMOS QUAD
2-CHANNEL MULTIPLEXER (INVERTING)
fabricated with sub-micron silicon gate and
double-layer metal wiring C
2
MOS technology. It is
ideal for low power and low noise 3.3V
applications.
It consists of four 2-input d igital multiplexers with
common select and strobe inputs. When STROBE
input is held high selection of data is inhibit and all
the outputs become high. The SELECT decoding
determines whether the A or B inputs get routed to
their corresponding Y outputs.
All inputs and outputs are equipped with
protection circuits against stat ic discharge, giving
them 2KV ESD immunity and transient excess
voltage.
