HC157
DESCRIPTION
The M54/74HC157 and the M54/74HC158 are high
speed CMOS QUAD 2-CHANNEL MULTIPLEXER’s fabricated with silicon gate C2MOS technology. They achieve the high speed operation
similar to equivalent LSTTL while maintaining the
CMOS low power dissipation.
These devices consist of four 2-input digital multiplexers with common select and strobe inputs. The
HC158 is an inverting multiplexer while the HC157
is a non-inverting multiplexer. When the STROBE
input is held High, selection of data is inhibited and
all the outputs become Low in the M74HC157 and
High in the M74HC158. The SELECT decoding
determines whether the A or B inputs get routed to
their corresponding Y outputs. All inputs are
equipped with protection circuits against static discharge and transient excess voltage.

(*) CPD is defined as the value of the IC’s internal equivalent capacitance which is calculated from the operating current consumption without load.
(Refer to Test Circuit). Average operting current can be obtained by the following equation. ICC(opr) = CPD •VCC •fIN + ICC/4 (per channel)
