DESCRIPTION
The 74ACT158 is an advanced high-speed CMOS
QUAD 2-CHANNEL MULTIPLEXER fabricated
with sub-micron silicon gate and double-layer
metal wiring C2MOS tecnology.
It consists of four 2-input digital multiplexer with
common select and strobe inputs. It is an inverting
multiplexer. When the 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.
The device is designed to interface directly High
Speed CMOS systems with TTL, NMOS and
CMOS output voltage levels.
All inputs and outputs are equipped with
protection circuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.

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/n (per circuit)

C L = 50pF or equivalent (includes jig and probe capacitance)
R L = R1 = 500Ω or equivalent
