74ALVC16721
Low Voltage 20-Bit D-Type Flip-Flops
with 3.6V Tolerant Inputs and Outputs
General Description
The ALVC16721 contains twenty non-inverting D-type
flip-flops with 3-STATE outputs and is intended for bus ori-
ented applications.
The 74ALVC16721 is designed for low voltage (1.65V to
3.6V) V
The 74ALVC16721 is fabricated with an advanced CMOS
technology to achieve high speed operation while maintain-
ing low CMOS power dissipation.
Ordering Code:
Device also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering code.

... LOW-to-HIGH transition Functional Description The 74ALVC16721 contains twenty D-type flip-flops with 3-STATE standard outputs. The twenty flip-flops will store the state of their individual D-type inputs that meet the setup and hold time requirements on the LOW-HIGH Clock (CLK) transition, when the Clock-Enable (CE) is LOW. The 3-STATE standard outputs are controlled by the Output Enable (OE) ...
