Manufacturer Part Number
tc74vcx16721ft
Description
Low-voltage 20-bit D-type Flip-flop With 3.6-v Tolerant Inputs And Outputs
Manufacturer
TOSHIBA Semiconductor CORPORATION
Datasheet
Low-Voltage 20-Bit D-Type Flip-Flop with 3.6-V Tolerant Inputs and Outputs
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.
up to 3.6 V.
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
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.
Features
The TC74VCX16721FT is a high-performance CMOS 20-bit
It is also designed with overvoltage tolerant inputs and outputs
The TC74VCX16721FT is edge-triggered D-type flip-flop with
All inputs are equipped with protection circuits against static discharge.
