Quiescent supply current
VCC = 3.6V; Outputs High, VI = GND or VCC, IO = 0
VCC = 3.6V; Outputs Low, VI = GND or VCC, IO = 0
∆ICC
Additional supply current per
input pin2
VCC = 3V to 3.6V; One input at VCC -0.6V,
Other inputs at VCC or GND
NOTES:
1. All typical values are at VCC = 3.3V and Tamb = 25°C.
2. This is the increase in supply current for each input at the specified voltage level other than VCC or GND
3. Unused pins at VCC or GND.
4. For valid test results, data must not be loaded into the flip-flops (or latches) after applying the power.
5. This is the bus hold overdrive current required to force the input to the opposite logic state.

Definitions
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.
Limiting values definition — Limiting values given are in accordance with the Absolute Maximum Rating System (IEC 134). 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.

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.
Right to make changes — Philips Semiconductors reserves the right to make changes, without notice, in the products, including circuits, standard
cells, and/or software, described or contained herein in order to improve design and/or performance. Philips Semiconductors assumes no
responsibility or liability for the use of any of these products, conveys no license or title under any patent, copyright, or mask work right to these
