TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC74HC05AP, TC74HC05AF
Hex Inverter (open drain)
The TC74HC05A is a high speed CMOS INVERTER fabricated
with silicon gate C2MOS technology.
It achieves the high speed operation similar to equivalent
LSTTL while maintaining the CMOS low power dissipation.
Pin configuration and function are the same as the
TC74HC04A, but the TC74HC05A has high performance MOS
N-channel transistor (open-drain) outputs.
This device can, therefore, with a suitable pull-up resistors, be
used in wired-AND, LED drive and other applications.
All inputs are equipped with protection circuits against static
discharge or transient excess voltage.
Features
• High speed: tpz = 8 ns (typ.) at VCC = 5 V
• Low power dissipation: ICC = 1 μA (max) at Ta = 25°C
• High noise immunity: VNIH = VNIL = 28% VCC (min)
• Output drive capability: 10 LSTTL loads
• Wide operating voltage range: VCC (opr) = 2 to 6 V
• Open drain structure.
• Pin and function compatible with 74LS05

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.
