HEF4555B

1-of-4 decoder/demultiplexer

Rev. 7 — 15 October 2018 Product data sheet

1. General description

The HEF4555B contains two 1-of-4 decoders/demultiplexers. Each has two address inputs (nA0

and nA1, an active LOW enable input (nE) and four mutually exclusive outputs which are active

HIGH (nY0 to nY3). When used as a decoder, nE when HIGH, forces nY0 to nY3 LOW. When used

as a demultiplexer, the appropriate output is selected by the information on nA0 and nA1 with nE

as data input. All unselected outputs are LOW.

It operates over a recommended VDD power supply range of 3 V to 15 V referenced to VSS (usually

ground). Unused inputs must be connected to VDD, VSS, or another input.

2. Features and benefits

•Fully static operation

•5 V, 10 V, and 15 V parametric ratings

•Standardized symmetrical output characteristics

•Specified from -40 °C to +85 °C

•Complies with JEDEC standard JESD 13-B

3. Applications

•Code conversion

•Address decoding

•Demultiplexing: when using the enable input as data input

4. Ordering information

Table 1. Ordering information

All types operate from -40 °C to +85 °C.

PD can be calculated from the formulas shown. VSS = 0 V; tr = tf ≤ 20 ns; Tamb = 25 °C.

Symbol Parameter VDD Typical formula for PD (μW) Where:

Draft — The document is a draft version only. The content is still under

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

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.

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.

Quick reference data — The Quick reference data is an extract of the

product data given in the Limiting values and Characteristics sections of this

document, and as such is not complete, exhaustive or legally binding.

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.

Nexperia 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 Nexperia 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). Nexperia 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 — Nexperia products are

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
