ORDERING INFORMATION
Philips Semiconductors Product specification
74ABT20Dual 4-input NAND gate
ABSOLUTE MAXIMUM RATINGS1, 2
NOTES: Stresses beyond those listed may cause permanent damage to the device. These are stress ratings only and functional operation of the
device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to
absolute-maximum-rated conditions for extended periods may affect device reliability. The performance capability of a high-performance integrated circuit in conjunction with its thermal environment can create junction
temperatures which are detrimental to reliability. The maximum junction temperature of this integrated circuit should not exceed 150°C. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
RECOMMENDED OPERATING CONDITIONS
DC ELECTRICAL CHARACTERISTICS
NOTES: Not more than one output should be tested at a time, and the duration of the test should not exceed one second. This is the increase in supply current for each input at 3.4V. For valid test results, data must not be loaded into the flip-flop or latch after applying the power.

AC CHARACTERISTICSGND = 0V; tR = tF = 2.5ns; CL = 50pF, RL = 500Ω
NOTE: Skew is defined as the absolute value of the difference between the actual propagation delay for any two separate outputs of the same
device. The specification applies to any outputs switching in the the same direction, either HIGH–to-LOW (tOSHL) or LOW-to-HIGH (tOSLH);
parameter guaranteed by design.
