Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers
will need to change in order to meet ON Semiconductor’s system requirements. Since the ON Semiconductor
product management systems do not have the ability to manage part nomenclature that utilizes an underscore
(_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain
device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated
device numbers. The most current and up-to-date ordering information can be found at www.onsemi.com. Please
email any questions regarding the system integration to Fairchild_questions@onsemi.com.

74VHCT74A
Dual D-Type Flip-Flop with Preset and Clear
Features
General Description
n High speed: fMAX = 160MHz (Typ.) at TA = 25°C
n High noise immunity: VIH = 2.0V, VIL = 0.8V
n Power down protection is provided on all inputs and
The VHCT74A is an advanced high speed CMOS Dual
D-Type Flip-Flop fabricated with silicon gate CMOS tech-
nology. It achieves the high speed operation similar to
equivalent Bipolar Schottky TTL while maintaining the
CMOS low power dissipation. The signal level applied to
the D INPUT is transferred to the Q OUTPUT during the
positive going transition of the CK pulse. CLR and PR
are independent of the CK and are accomplished by set-
ting the appropriate input LOW.
outputs
n Low power dissipation: ICC = 2µA (Max.) at TA = 25°C
n Pin and function compatible with 74HCT74
Protection circuits ensure that 0V to 7V can be applied to
the input pins without regard to the supply voltage and to
the output pins with VCC = 0V. These circuits prevent
device destruction due to mismatched supply and input/
output voltages. This device can be used to interface 3V
to 5V systems and two supply systems such as battery
backup.

Absolute Maximum Ratings
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be
operable above the recommended operating conditions and stressing the parts to these levels is not recommended.
In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability.
The absolute maximum ratings are stress ratings only.

Notes:

6. CPD is defined as the value of 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 / 2 (per flip-flop).
