TC74LCX74F/FN/FT
TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC74LCX74F,TC74LCX74FN,TC74LCX74FT
Low-Voltage Dual D-Type Flip-Flop with 5-V Tolerant Inputs and Outputs
Note: xxxFN (JEDEC SOP) is not available in
Japan.
The TC74LCX74F/FN/FT is a high-performance CMOS D-type
flip-flop. Designed for use in 3.3-V systems, it achieves
TC74LCX74F
high-speed operation while maintaining the CMOS low power
dissipation.
The device is designed for low-voltage (3.3 V) V
applications,
CC
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.
