74LVC1G123-Q100

Single retriggerable monostable multivibrator;

Schmitt trigger inputs

Rev. 3 — 2 November 2018

Product data sheet

1. General description

The 74LVC1G123-Q100 is a single retriggerable monostable multivibrator with Schmitt trigger

inputs. Output pulse width is controlled by three methods:

1. The basic pulse is programmed by selection of an external resistor (R_EXT) and capacitor (C_EXT).

2. Once triggered, the basic output pulse width may be extended by retriggering the gated active

LOW-going edge input (A) or the active HIGH-going edge input (B). By repeating this process,

the output pulse period (Q = HIGH) can be made as long as desired. Alternatively an output

delay can be terminated at any time by a LOW-going edge on input CLR, which also inhibits the

triggering.

3. An internal connection from CLR to the input gates makes it possible to trigger the circuit by a

HIGH-going signal at input CLR.

Inputs can be driven from either 3.3 V or 5 V devices. This feature allows the use of these devices

as translators in a mixed 3.3 V and 5 V environment. Schmitt trigger inputs, makes the circuit highly

tolerant to slower input rise and fall times.

This device is fully specified for partial power-down applications using I_OFF. The I_OFFcircuitry

disables the output, preventing the damaging backflow current through the device when it is

powered down.

This product has been qualified to the Automotive Electronics Council (AEC) standard Q100

(Grade 1) and is suitable for use in automotive applications.

t_W= K x R_EXTx C_EXT, where:

t_W= typical output pulse width in ns;

R_EXT= external resistor in kΩ;

C_EXT= external capacitor in pF;

K = constant = 1; see Fig. 13 for typical "K" factor as function of V_CC

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

Definitions

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

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.

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

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

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.

No offer to sell or license — Nothing in this document may be interpreted

or construed as an offer to sell products that is open for acceptance or the

grant, conveyance or implication of any license under any copyrights, patents
