FEATURES:
DESCRIPTION:
•
•
•
•
•
The IDT54/74FCT151T/AT/CT are high-speed 8-input multiplexers built using an advanced dual metal CMOS technology. They select one bit of data from up to eight sources under
the control of three select inputs. Both assertion and negation
outputs are provided.
The IDT54/74FCT151T/AT/CT has a common Active-LOW
enable (E) input. When E is LOW, data from one of eight inputs
is routed to the complementary outputs according to the 3-bit
code applied to the Select (S0-S2) inputs. A common application of the ‘FCT151 is data routing from one of eight
sources.

NOTES:
1. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause permanent damage to the device. This is a stress rating
only and functional operation of the device at these or any other conditions
above those indicated in the operational sections of this specification is
not implied. Exposure to absolute maximum rating conditions for
extended periods may affect reliability. No terminal voltage may exceed
VCC by +0.5V unless otherwise noted.
2. Input and VCC terminals only.
3. Outputs and I/O terminals only.
