TC74AC08P/F/FT
TOSHIBA CMOS Digital Integrated Circuit
Silicon Monolithic
TC74AC08P, TC74AC08F, TC74AC08FT
Quad 2-Input AND Gate
The TC74AC08 is an advanced high speed CMOS 2-INPUT
AND GATE fabricated with silicon gate and double-layer metal
wiring C
2
MOS technology.
It achieves the high speed operation similar to equivalent
Bipolar Schottky TTL while maintaining the CMOS low power
dissipation.
The internal circuit is composed of 2 stages including buffer
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°C
to 65°C. From Ta = 65°C to 85°C a derating factor of
−10
mW/°C
should be applied up to 300 mW.
