74LVT574 • 74LVTH574

Low Voltage Octal D-Type Flip-Flop

with 3-STATE Outputs

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 appli-

cations. 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.

Features
