8-input multiplexer; 3-state
Rev. 2 — 15 July 2019
Product data sheet
1. General description
The 74HC251-Q100; 74HCT251-Q100 is an 8-bit multiplexer with eight binary inputs (I0 to I7),
three select inputs (S0 to S2) and an output enable input (OE). The select inputs select one of the
eight binary inputs and route it to the complementary outputs (Y and Y). A HIGH on OE causes the
outputs to assume a high-impedance OFF-state. Inputs include clamp diodes that enable the use
of current limiting resistors to interface inputs to voltages in excess of VCC
.
This product has been qualified to the Automotive Electronics Council (AEC) standard Q100
(Grade 1) and is suitable for use in automotive applications.

PD = CPD × VCC2 × fi × N + ∑(CL × VCC2 × fo) where:
fi = input frequency in MHz;

CL = output load capacitance in pF;
VCC = supply voltage in V;
N = number of inputs switching;
∑(CL × VCC2 × fo) = sum of outputs.

internal review and subject to formal approval, which may result in
modifications or additions. Nexperia does not give any representations or
warranties as to the accuracy or completeness of information included herein
and shall have no liability for the consequences of use of such information.
Limiting values — Stress above one or more limiting values (as defined in
the Absolute Maximum Ratings System of IEC 60134) will cause permanent
damage to the device. Limiting values are stress ratings only and (proper)
operation of the device at these or any other conditions above those
given in the Recommended operating conditions section (if present) or the
Characteristics sections of this document is not warranted. Constant or
repeated exposure to limiting values will permanently and irreversibly affect
the quality and reliability of the device.
Short data sheet — A short data sheet is an extract from a full data sheet
with the same product type number(s) and title. A short data sheet is
intended for quick reference only and should not be relied upon to contain
detailed and full information. For detailed and full information see the relevant
full data sheet, which is available on request via the local Nexperia sales
office. In case of any inconsistency or conflict with the short data sheet, the
full data sheet shall prevail.

sold subject to the general terms and conditions of commercial sale, as
published at http://www.nexperia.com/profile/terms, unless otherwise agreed
in a valid written individual agreement. In case an individual agreement is
concluded only the terms and conditions of the respective agreement shall
apply. Nexperia hereby expressly objects to applying the customer’s general
terms and conditions with regard to the purchase of Nexperia products by
customer.
Product specification — The information and data provided in a Product
data sheet shall define the specification of the product as agreed between
Nexperia and its customer, unless Nexperia and customer have explicitly
