TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC74HC375AP,TC74HC375AF,TC74HC375AFN
4-Bit D Type Latch
The TC74HC375A is a high speed CMOS D-TYPE LATCH
fabricated with silicon gate C
It achieves the high speed operation similar to equivalent
LSTTL while maintaining the CMOS low power dissipation.
It contains two groups of 2-bit latches controlled by an enable
input (G1·2 or G3·4) and each group can be used in different
circuits.
Data applied to the data inputs are transferred to the Q and
Q outputs whin the enable inputs is high. When the enable
input is low, the outputs are not affected.
All inputs are equipped with protection circuits against static
discharge or transient excess voltage.

Absolute Maximum Ratings (Note 1)
Characteristics Symbol Rating Unit
Supply voltage range VCC −0.5 to 7 V
DC input voltage VIN −0.5 to VCC + 0.5 V
DC output voltage V
Input diode current IIK ±20 mA
Output diode current IOK ±20 mA

Power dissipation PD 500 (DIP) (Note 2)/180 (SOP) mW
Storage temperature T
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).
