TC74HC21AP,TC74HC21AF,TC74HC21AFN
Dual 4-Input AND Gate
Note: xxxFN (JEDEC SOP) is not available in
Japan.
The TC74HC21A is a high speed CMOS 4-INPUT AND GATE
fabricated with silicon gate C2MOS technology.
TC74HC21AP
TC74HC21AF
TC74HC21AFN
It achieves the high speed operation similar to equivalent
LSTTL while maintaining the CMOS low power dissipation.
The internal circuit is composed of 4 stages including buffer an
output, which provide high noise immunity and stable output.
All inputs are equipped with protection circuits against static
discharge or transient excess voltage.

Note 1: Exceeding any of the absolute maximum ratings, even briefly, lead to deterioration in IC performance or
even destruction.
Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the
significant change in temperature, etc.) may cause this product to decrease in the reliability significantly
even if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute
maximum ratings and the operating ranges.
Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook
(“Handling Precautions”/“Derating Concept and Methods”) and individual reliability data (i.e. reliability test
report and estimated failure rate, etc).
Note 2: 500 mW in the range of Ta = −40 to 65°C. From Ta = 65 to 85°C a derating factor of −10 mW/°C shall be
applied until 300 mW.
