74LVC821A
10-bit D-type flip-flop with 5 V tolerant inputs/outputs;
positive-edge trigger; 3-state
Rev. 03 — 11 May 2004
Product data sheet
1. General description
The 74LVC821A is a high performance, low power, low voltage Si-gate CMOS device and
superior to most advanced CMOS compatible TTL families.
Inputs can be driven from either 3.3 V or 5 V devices. In 3-state operation, outputs can
handle 5 V. This feature allows the use of these devices as translators in a mixed 3.3 V
and 5 V environment.
The 74LVC821A is a 10-bit D-type flip-flop featuring separate D-type inputs for each
flip-flop and 3-state outputs for bus-oriented applications. A clock input (pin CP) and an
output enable input (pin OE) are common to all flip-flops. The ten flip-flops will store the
state of their individual D-inputs that meet the set-up and hold times requirements on the
LOW-to-HIGH CP transition. When pin OE is LOW, the contents of the ten flip-flops is
available at the outputs.
When pin OE is HIGH, the outputs go to the high-impedance OFF-state. Operation of the
OE inputs does not affect the state of the flip-flops.

[1]
CPD is used to determine the dynamic power dissipation (PD in µW).
PD = CPD × VCC2 × fi × N + Σ (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 = total load switching outputs;
Σ (CL × VCC2 × fo) = sum of the outputs.
[2]
The condition is VI = GND to VCC.

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 µW).
PD = CPD × VCC2 × fi × N + Σ (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 = total load switching outputs;
Σ (CL × VCC2 × fo) = sum of the outputs.
[5]
The condition is VI = GND to VCC.

16. Definitions
17. Disclaimers
Short-form specification — The data in a short-form specification is
extracted from a full data sheet with the same type number and title. For
detailed information see the relevant data sheet or data handbook.
Life support — These products are not designed for use in life support
appliances, devices, or systems where malfunction of these products can
reasonably be expected to result in personal injury. Philips Semiconductors
customers using or selling these products for use in such applications do so
at their own risk and agree to fully indemnify Philips Semiconductors for any
damages resulting from such application.
Limiting values definition — Limiting values given are in accordance with
the Absolute Maximum Rating System (IEC 60134). Stress above one or
more of the limiting values may cause permanent damage to the device.
These are stress ratings only and operation of the device at these or at any
other conditions above those given in the Characteristics sections of the
specification is not implied. Exposure to limiting values for extended periods
may affect device reliability.
Application information — Applications that are described herein for any
of these products are for illustrative purposes only. Philips Semiconductors
make no representation or warranty that such applications will be suitable for
the specified use without further testing or modification.
Right to make changes — Philips Semiconductors reserves the right to
make changes in the products - including circuits, standard cells, and/or
software - described or contained herein in order to improve design and/or
performance. When the product is in full production (status ‘Production’),
relevant changes will be communicated via a Customer Product/Process
Change Notification (CPCN). Philips Semiconductors assumes no
