Octal D-Type Flip-Flop
TC74AC377P
The TC74AC377 is an advanced high speed CMOS OCTAL
D-TYPE FLIP FLOP fabricated with silicon gate and
double-layer metal wiring C2MOS technology.
It achieves the high speed operation similar to equivalent
Bipolar Schottky TTL while maintaining the CMOS low power
dissipation.
This 8-bit D-type flip-flop is controlled by a clock input (CK)
and an enable input ( G )
The signal level applied to the D inputs are transferred to Q
outputs during the positive going transition of CK.
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 should be
applied up to 300 mW.

CPD is defined as the value of the internal equivalent capacitance which is calculated from the operating
current consumption without load.
Average operating current can be obtained by the equation:
ICC (opr) = CPD・VCC・fIN + ICC/8 (per F/F)
And the total CPD when n pcs. of flip flop operate can be gained by the following equation:
CPD (total) = 20 + 10・n
