General Description

The LVT574 and LVTH574 are high-speed, low-power

octal D-type flip-flop featuring separate D-type inputs for

each flip-flop and 3-STATE outputs for bus-oriented

applications. A buffered Clock (CP) and Output Enable

(OE) are common to all flip-flops.

The LVTH574 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)

interface to a 5V environment. The LVT574 and

LVTH574 are fabricated with an advanced BiCMOS

technology to achieve high speed operation similar to 5V

ABT while maintaining a low power dissipation.

Ordering Information

Device also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering number.

All packages are lead free per JEDEC: J-STD-020B standard.
