74HC238-Q100; 74HCT238-Q100
3-to-8 line decoder/demultiplexer
Rev. 1 — 19 February 2013
Product data sheet
1. General description
The 74HC_HCT238_Q100 decodes three binary weighted address inputs (A0, A1 and
A2) to eight mutually exclusive outputs (Y0 to Y7). The device features three enable
inputs (E1, E2 and E3). Every output is LOW unless E1 and E2 are LOW and E3 is HIGH.
This multiple enable function allows easy parallel expansion to a 1-of-32 (5 to 32 lines)
decoder with just four 74HC_HCT238_Q100 ICs and one inverter. The
74HC_HCT238_Q100 can be used as an eight output demultiplexer by using one of the
active LOW enable inputs as the data input and the remaining enable inputs as strobes.
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.

(1) This is not a supply pin. The substrate is attached to this
pad using conductive die attach material. There is no
electrical or mechanical requirement to solder this pad.
However, if it is soldered, the solder land should remain
floating or be connected to GND.

CPD is used to determine the dynamic power dissipation (PD in W):
PD = CPD  VCC2  fi  N +  (CL  VCC2  fo) where:
fi = input frequency in MHz;
fo = output 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.

Product data sheet
Suitability for use in automotive applications — This NXP
Semiconductors product has been qualified for use in automotive
applications. Unless otherwise agreed in writing, the product is not designed,
authorized or warranted to be suitable for use in life support, life-critical or
safety-critical systems or equipment, nor in applications where failure or
malfunction of an NXP Semiconductors product can reasonably be expected
to result in personal injury, death or severe property or environmental
damage. NXP Semiconductors and its suppliers accept no liability for
inclusion and/or use of NXP Semiconductors products in such equipment or
applications and therefore such inclusion and/or use is at the customer's own
risk.
Applications — Applications that are described herein for any of these
products are for illustrative purposes only. NXP Semiconductors makes no
representation or warranty that such applications will be suitable for the
specified use without further testing or modification.
Customers are responsible for the design and operation of their applications
and products using NXP Semiconductors products, and NXP Semiconductors
accepts no liability for any assistance with applications or customer product
design. It is customer’s sole responsibility to determine whether the NXP
Semiconductors product is suitable and fit for the customer’s applications and
products planned, as well as for the planned application and use of
customer’s third party customer(s). Customers should provide appropriate
design and operating safeguards to minimize the risks associated with their
applications and products.
NXP Semiconductors does not accept any liability related to any default,
damage, costs or problem which is based on any weakness or default in the
customer’s applications or products, or the application or use by customer’s
third party customer(s). Customer is responsible for doing all necessary
testing for the customer’s applications and products using NXP
Semiconductors products in order to avoid a default of the applications and
the products or of the application or use by customer’s third party
customer(s). NXP does not accept any liability in this respect.
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.
Terms and conditions of commercial sale — NXP Semiconductors
products are sold subject to the general terms and conditions of commercial
sale, as published at http://www.nxp.com/profile/terms, unless otherwise
agreed in a valid written individual agreement. In case an individual
