74LVTH273
Low Voltage Octal D-Type Flip-Flop with Clear
General Description
The LVTH273 is a high-speed, low-power positive-edge-
triggered octal D-type flip-flop featuring separate D-type
inputs for each flip-flop. A buffered Clock (CP) and Clear
(CLR) are common to all flip-flops.
The state of each D-type input, one setup time before the
positive clock transition, is transferred to the corresponding
flip-flop’s output.
The LVTH273 data inputs include bushold, eliminating the
need for external pull-up resistors to hold unused inputs.
These octal flip-flops are designed for low-voltage (3.3V)
V
interface to a 5V environment. The LVTH273 is fabricated
with an advanced BiCMOS technology to achieve high
speed operation similar to 5V ABT while maintaining low
power dissipation.
Ordering Code:
Device also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering code.
Pb-Free package per JEDEC J-STD-020B.
Note 1: “_NL” indicates Pb-Free package (per JEDEC J-STD-020B). Device available in Tape and Reel only.
