74LVT374 鈥?74LVTH374
Low Voltage Octal D-Type Flip-Flop
with 3-STATE Outputs
General Description
The LVT374 and LVTH374 are high-speed, low-power
octal D-type flip-flops 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 LVTH374 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)

applications, but with the capability to provide a TTL
interface to a 5V environment. The LVT374 and LVTH374
are fabricated with an advanced BiCMOS technology to
achieve high speed operation similar to 5V ABT while
maintaining low power dissipation.
