74HC42

BCD to decimal decoder (1-of-10)

Rev. 3 — 27 September 2016

Product data sheet

1. General description

The 74HC42 is a one of ten BCD to decimal decoder. It accepts four BCD inputs (0A to

3A) and provides ten mutually exclusive outputs (0Y to 9Y). The logic design ensures that

all outputs are HIGH when binary codes greater than nine are applied to the inputs. The

most significant input (3A) produces an useful inhibit function when the device is used as

a 1-of-8 decoder. The 3A input can also be used as the data input in an 8-output

demultiplexer application. Inputs include clamp diodes. This enables the use of current

limiting resistors to interface inputs to voltages in excess of V_CC

2. Features and benefits

 Complies with JEDEC standard no. 7A

 Input levels:

 For 74HC42: CMOS level

 Mutually exclusive outputs

 1-of-8 demultiplexing capability

 Outputs disabled for input codes above nine

 ESD protection:

 HBM JESD22-A114F exceeds 2000 V

 MM JESD22-A115-A exceeds 200 V

 Specified from 40 C to +85 C and 40 C to +125 C

Suitability for use — Nexperia products are not designed,

15.2 Definitions

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 a Nexperia product can reasonably be expected

to result in personal injury, death or severe property or environmental

damage. Nexperia and its suppliers accept no liability for

inclusion and/or use of Nexperia products in such equipment or

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.

Applications — Applications that are described herein for any of these

products are for illustrative purposes only. Nexperia 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 Nexperia products, and Nexperia

accepts no liability for any assistance with applications or customer product

design. It is customer’s sole responsibility to determine whether the Nexperia

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.

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 agreed otherwise in writing. In no event however,

shall an agreement be valid in which the Nexperia product is

deemed to offer functions and qualities beyond those described in the

Product data sheet.
