74LVC373A
Octal D-type transparent latch with 5 V tolerant
inputs/outputs; 3-state
Rev. 3 — 22 November 2012
Product data sheet
1. General description
The 74LVC373A consists of eight D-type transparent latches, featuring separate D-type
inputs for each latch and 3-state true outputs for bus-oriented applications. A latch enable
input (pin LE) and an output enable input (pin OE) are common to all internal latches.
When pin LE is HIGH, data at the D-inputs (pins D0 to D7) enters the latches. In this
condition, the latches are transparent, that is, a latch output will change each time its
corresponding D-input changes. When pin LE is LOW, the latches store the information
that was present at the D-inputs one set-up time preceding the HIGH-to-LOW transition of
pin LE.
When pin OE is LOW, the contents of the eight latches are available at the Q-outputs (pins
Q0 to Q7). When pin OE is HIGH, the outputs go to the high-impedance OFF-state.
Operation of input pin OE does not affect the state of the latches.
Inputs can be driven from either 3.3 V or 5 V devices. When disabled, up to 5.5 V can be
applied to the outputs. These features allow the use of these devices as translators in
mixed 3.3 V and 5 V applications.
The 74LVC373A is functionally identical to the 74LVC573A, but has a different pin
arrangement.
2. Features and benefits

(1) This is not a supply pin. The substrate is attached to this
pad using conductive die attach material. There is no
electrical or mechanical requirement to solder this pad.
However, if it is soldered, the solder land should remain
floating or be connected to GND.

Skew between any two outputs of the same package switching in the same direction. This parameter is guaranteed by design.
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 Volts
N = number of inputs switching
(CL VCC2 fo) = sum of the outputs

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.

Product data sheet
Suitability for use — Nexperia products are 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 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
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. 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 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.
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 or
other industrial or intellectual property rights.
