DESCRIPTION
The M54/74HC257 and the M54/74HC258 are high
speed CMOS MULTIPLEXERs fabricated with sili2
con gate C MOS technology.
They have the same high speed performance of
LSTTL combined with true CMOS low power consumption.
These IC’s are composed of an independent 2channel multiplexer with common SELECT and ENABLE INPUT.
HC258
The M54/74HC258 is an inverting multiplexer while
the M54/74HC257 is a non-inverting multiplexer.
When the ENABLE INPUT is held ”High”, outputs of
both IC’s become high-impedance state. If SELECT
INPUT is held ”Low”, ”A” data is selected, when SELECT INPUT is high ”H”, ”B” data is chosen.
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)
