DESCRIPTION

The M74HCT157 is an high speed CMOS QUAD
2 CHANNEL MULTIPLEXER fabricated with
silicon gate C2 MOS technology.
This device consists of four 2-input digital
multiplexer with common select and strobe inputs.
When the STROBE(ST) input is held high,
selection of data is inhibited and all the outputs
become low. 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.

ABSOLUTE MAXIMUM RATINGS

Absolute Maximum Ratings are those values beyond which damage to the device may occur. Functional operation under these conditions is
not implied
(*) 500mW at 65 °C; derate to 300mW by 10mW/°C from 65°C to 85°C

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 chan-
nel)
TEST CIRCUIT

CL = 50pF or equivalent (includes jig and probe capacitance)
RT = ZOUT of pulse generator (typically 50Ω)
WAVEFORM : PROPAGATION DELAY TIMES (f=1MHz; 50% duty cycle)
