74HC7541; 74HCT7541
Octal Schmitt trigger buffer/line driver; 3-state
Rev. 3 — 25 July 2011
Product data sheet
1. General description
The 74HC7541; 74HCT7541 is a high-speed Si-gate CMOS device and is pin compatible
with Low-power Schottky TTL (LSTTL). It is specified in compliance with JEDEC standard
No. 7A.
The 74HC7541; 74HCT7541 provides eight non-inverting buffer/line drivers with 3-state
outputs and Schmitt-trigger action. The 3-state outputs are controlled by the output enable
inputs OE1 and OE2. A HIGH on OEn causes the outputs to assume a high-impedance
OFF-state. Schmitt trigger action on the data inputs transforms slowly changing input
signals into sharply defined, jitter-free output signals.
The 74HC7541; 74HCT7541 is identical to the 74HC541; 74HCT541 but has hysteresis
on the data inputs.
2. Features and benefits
 Non-inverting outputs
 Low-power dissipation
 ESD protection:
 HBM JESD22-A114F exceeds 2000 V
 MM JESD22-A115-A exceeds 200 V
 Multiple package options
 Specified from 40 C to +85 C and from 40 C to +125 C

The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
For DIP20 packages: above 70 C the value of Ptot derates linearly with 12 mW/K.
For SO20 packages: above 70 C the value of Ptot derates linearly with 8 mW/K.
For SSOP20 and TSSOP20 packages: above 60 C the value of Ptot derates linearly with 5.5 mW/K.

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.

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.
Product specification — The information and data provided in a Product
data sheet shall define the specification of the product as agreed between
NXP Semiconductors and its customer, unless NXP Semiconductors and
customer have explicitly agreed otherwise in writing. In no event however,
shall an agreement be valid in which the NXP Semiconductors product is
deemed to offer functions and qualities beyond those described in the
Product data sheet.

Suitability for use in automotive applications — This NXP
Semiconductors product has been qualified for use in automotive
applications. The product is not designed, authorized or warranted to be
74HC_HCT7541
Product data sheet
suitable for use in medical, military, aircraft, space or life support 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 accepts 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
