Low-Voltage Dual D-Type Flip-Flop with 5-V Tolerant Inputs and Outputs
The TC74LCX74 is a high-performance CMOS D-type flip-flop.
Designed for use in 3.3-V systems, it achieves high-speed
operation while maintaining the CMOS low power dissipation.
The device is designed for low-voltage (3.3 V) VCC applications,
but it could be used to interface to 5-V supply environment for
inputs.
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.
All inputs are equipped with protection circuits against static
discharge.
Note: xxxFN (JEDEC SOP) is not available in
Japan.
