TC74VCX2574FT/FK
TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC74VCX2574FT, TC74VCX2574FK
Low-Voltage Octal D-Type Flip-Flop with 3.6-V Tolerant Inputs and Outputs
The TC74VCX2574 is a high-performance CMOS octal D-type
flip-flop. Designed for use in 1.8-V, 2.5-V or 3.3-V systems, it
achieves high-speed operation while maintaining the CMOS low
power dissipation.
It is also designed with overvoltage tolerant inputs and outputs
up to 3.6 V.
This 8 bit D-type flip-flop is controlled by a clock input (CK)
and an output enable input ( OE ). When the OE input is high,
the eight outputs are in a high-impedance state. The 26-series
resistor helps reducing output overshoot and undershoot without
external resistor.
All inputs are equipped with protection circuits against static
discharge.
