| TC74VCX16721FT TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74VCX16721FT Low-Voltage 20-Bit D-Type Flip-Flop with 3.6-V Tolerant Inputs and Outputs The TC74VCX16721FT is a high-performance CMOS 20-bit 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. The TC74VCX16721FT is edge-triggered D-type flip-flop with qualified clock storage. On the positive transition of the clock (CK) input, the device provides true data at the Q outputs if the clock-enable (CKEN) input is low. If CKEN is high, no data is Weight: 0.25 g (typ.) stored. When the OE input is high, the outputs are in a high-impedance state. This device is designed to be used with 3-state memory address drivers, etc. All inputs are equipped with protection circuits against static discharge.
