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)
VCC applications, but with the capability to provide a TTL
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
s Input and output interface capability to systems at 5V
VCC
s Bushold data inputs eliminate the need for external pull-
up resistors to hold unused inputs (74LVTH574), also
available without bushold feature (74LVT574).
s Live insertion/extraction permitted
s Power Up/Down high impedance provides glitch-free
bus loading
s Outputs source/sink 32 mA/+64 mA
s Functionally compatible with the 74 series 574
s Latch-up performance exceeds 500 mA
