Dual retriggerable monostable multivibrator with reset
Rev. 1 — 23 May 2013
Product data sheet
1. General description
The 74AHC123A-Q100; 74AHCT123A-Q100 are high-speed Si-gate CMOS devices and
are pin compatible with Low-power Schottky TTL (LSTTL). They are specified in
compliance with JEDEC standard no. 7A.
The 74AHC123A-Q100; 74AHCT123A-Q100 are dual retriggerable monostable
multivibrators with output pulse width control by three methods. The selection of an
external resistor (Rext) and capacitor (Cext) program the basic pulse time. The external
resistor and capacitor are normally connected as shown in Figure 11.
Once triggered, the basic output pulse width may be extended by retriggering the gated
active LOW-going edge input (nA) or the active HIGH-going edge input (nB). By repeating
this process, the output pulse period (nQ = HIGH, nQ = LOW) can be made as long as
desired. Alternatively an output delay can be terminated at any time by a LOW-going edge
on input nRD, which also inhibits the triggering.
An internal connection from nRD to the input gate makes it possible to trigger the circuit by
a positive-going signal at input nRD as shown in Table 3. Figure 8 and Figure 9 illustrate
pulse control by retriggering and early reset. The values of the external timing
components Rext and Cext, determine the basic output pulse width. When Cext 10 nF, the
typical output pulse width is defined as: tW = Rext Cext where tW = pulse width in ns;
R
ext = external resistor in k; Cext = external capacitor in pF. Schmitt-trigger action at all
inputs makes the circuit highly tolerant to slower input rise and fall times.
This product has been qualified to the Automotive Electronics Council (AEC) standard
Q100 (Grade 1) and is suitable for use in automotive applications.

[1] Typical values are measured at nominal supply voltage (VCC = 3.3 V and VCC = 5.0 V).
[2] tpd is the same as tPLH and tPHL; Cext = 0 pF; Rext = 5 k.
[3] For Cext 10 nF, the typical value of the pulse width tW (s) = Cext (nF) Rext (k).
[4] CPD is used to determine the dynamic power dissipation PD (W).
PD = CPD VCC2 fi + (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.
[5] Cext has no limits.

Suitability for use in automotive applications — This NXP
15.2 Definitions
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.
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. NXP Semiconductors 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.
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 NXP Semiconductors 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
