Dual D-Type Flip-Flop with Preset and Clear
The TC74LVX74F/ FT is a high-speed CMOS D-flip flop
fabricated with silicon gate CMOS technology. Designed for use
in 3-V systems, it achieves high-speed operation while
maintaining the CMOS low power dissipation.
This device is suitable for low-voltage and battery operated
systems.
The signal level applied to the D input is transferred to Q
output during the positive going transition of the CK pulse.
CLR and PR are independent of the CK and are
accomplished by setting the appropriate input low.
An input protection circuit ensures that 0 to 5.5V can be
applied to the input pins without regard to the supply voltage.
This device can be used to interface 5V to 3V systems and two
supply systems such as battery back up. This circuit prevents
device destruction due to mismatched supply and input voltages.
Features
• High-speed: f_max = 145 MHz (typ.) (V_CC = 3.3 V)
• Low power dissipation: I_CC = 2 μA (max) (Ta = 25°C)
• Input voltage level: V_IL = 0.8 V (max) (V_CC = 3 V)
V_IH = 2.0 V (min) (V_CC = 3 V)
• Power-down protection provided on all inputs
• Balanced propagation delays: t_pLH ^∼− t_pHL
• Pin and function compatible with 74HC74
