8-Channel Multiplexer
Note:
xxxFN (JEDEC SOP) is not available in
Japan.
The TC74ACT151 is an advanced high speed CMOS
8-CHANNEL MULTIPLEXER fabricated with silicon gate and
double-layer metal wiring C
2
MOS technology.
It achieves the high speed operation similar to equivalent
Bipolar Schottky TTL while maintaining the CMOS low power
dissipation.
This device may be used as a level converter for interfacing
TTL or NMOS to High Speed CMOS. The inputs are compatible
with TTL, NMOS and CMOS output voltage levels.
One of eight date input signals (D0-D7) is selected by decoding
of the three-bit address input (A, B, C). The selected data appears
on two outputs: non-inverting (Y) and inverting (W).
The
STROBE
input provides two output conditions; a low
level on the
STROBE
input transferrs the selected data to the
outputs. A high level on the
STROBE
input sets the Y output
low and the W output high without regard to the data or select
input conditions.
All inputs are equipped with protection circuits against static
discharge or transient excess voltage.

Note 1: Exceeding any of the absolute maximum ratings, even briefly, lead to deterioration in IC performance or
even destruction.
Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the
significant change in temperature, etc.) may cause this product to decrease in the reliability significantly
even if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute
maximum ratings and the operating ranges.
Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook
(“Handling Precautions”/“Derating Concept and Methods”) and individual reliability data (i.e. reliability test
report and estimated failure rate, etc).
Note 2: 500 mW in the range of Ta
= −40
to 65°C. From Ta
=
65 to 85°C a derating factor of
−10
mW/°C should be
applied up to 300 mW.
