DESCRIPTIONThe M74HCT257 is an high speed CMOS QUAD
2 CHANNEL MULTIPLEXER (3-STATE)
fabricated with silicon gate C2 MOS technology.
This IC is composed of an independent 2-channel
multiplexer with common SELECT and ENABLE
(OE) input.
The M74HCT257 is a non-inverting multiplexer.
When the ENABLE input is held "High", outputs of
the IC become in a High-Impedance state. If
SELECT input is held low, "A" data is selected,
when SELECT is high , "B" data is chosen.
All inputs are equipped with protection circuits
against static discharge and transient excess
voltage.

CAPACITIVE CHARACTERISTICS 1) 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 operating current can be obtained by the following equation. ICC(opr) = CPD x VCC x fIN + ICC/4 (per
Channel)
TEST CIRCUIT CL = 50pF/150pF or equivalent (includes jig and probe capacitance)
R1 = 1KΩ or equivalent
RT = ZOUT of pulse generator (typically 50Ω)
