The application circuits and their parameters are for reference only and are not intended for use in actual design-ins.
Capacitors for VCC, input and output pins
1 000 pF capacitors are recommendable as bypass capacitor for V
CC
pin and coupling capacitors for input/output
pins.
Bypass capacitor for VCC pin is intended to minimize VCC pin’s ground impedance. Therefore, stable bias can be
supplied against VCC fluctuation.
Coupling capacitors for input/output pins are intended to minimize RF serial impedance and cut DC.
To get flat gain from 100 MHz up, 1 000 pF capacitors are assembled on the test circuit. [Actually, 1 000 pF
capacitors give flat gain at least 10 MHz. In the case of under 10 MHz operation, increase the value of coupling
capacitor such as 2 200 pF. Because the coupling capacitors are determined by the equation of C = 1/(2 π fZs).]

ILLUSTRATION OF APPLICATION CIRCUIT ASSEMBLED ON EVALUATION BOARD
(1) Observe precautions for handling because of electro-static sensitive devices.
(2) Form a ground pattern as wide as possible to prevent an increase in ground impedance (to prevent undesired
oscillation).
(3) Keep the track length of the ground pins as short as possible.
(4) Connect a bypass capacitor (e.g. 1000 pF) to the VCC pin.

document.
NEC Corporation does not assume any liability for infringement of patents, copyrights or other intellectual
property rights of third parties by or arising from use of a device described herein or any other liability arising
from use of such device. No license, either express, implied or otherwise, is granted under any patents,
copyrights or other intellectual property rights of NEC Corporation or others.
While NEC Corporation has been making continuous effort to enhance the reliability of its semiconductor devices,
the possibility of defects cannot be eliminated entirely. To minimize risks of damage or injury to persons or
property arising from a defect in an NEC semiconductor device, customers must incorporate sufficient safety
measures in its design, such as redundancy, fire-containment, and anti-failure features.
NEC devices are classified into the following three quality grades:
"Standard", "Special", and "Specific". The Specific quality grade applies only to devices developed based on
a customer designated "quality assurance program" for a specific application. The recommended applications
of a device depend on its quality grade, as indicated below. Customers must check the quality grade of each
device before using it in a particular application.
Standard: Computers, office equipment, communications equipment, test and measurement equipment,
audio and visual equipment, home electronic appliances, machine tools, personal electronic
equipment and industrial robots
Special: Transportation equipment (automobiles, trains, ships, etc.), traffic control systems, anti-disaster
systems, anti-crime systems, safety equipment and medical equipment (not specifically designed
for life support)
Specific: Aircrafts, aerospace equipment, submersible repeaters, nuclear reactor control systems, life
support systems or medical equipment for life support, etc.
The quality grade of NEC devices is "Standard" unless otherwise specified in NEC's Data Sheets or Data Books.
If customers intend to use NEC devices for applications other than those specified for Standard quality grade,
they should contact an NEC sales representative in advance.
Anti-radioactive design is not implemented in this product.
