description
These octal flip-flops are designed specifically for low-voltage (3.3-V) V

operation, but with the capability to
CC
The eight flip-flops of the ’LVTH574 devices are edge-triggered D-type flip-flops. On the positive transition of
the clock (CLK) input, the Q outputs are set to the logic levels set up at the data (D) inputs.
A buffered output-enable (OE) input can be used to place the eight outputs in either a normal logic state (high
or low logic levels) or a high-impedance state. In the high-impedance state, the outputs neither load nor drive
the bus lines significantly. The high-impedance state and increased drive provide the capability to drive bus
lines without need for interface or pullup components.
OE does not affect the internal operations of the flip-flops. Old data can be retained or new data can be entered
while the outputs are in the high-impedance state.
Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level.
When V is between 0 and 1.5 V, the devices are in the high-impedance state during power up or power down.
CC
However, to ensure the high-impedance state above 1.5 V, OE should be tied to V
through a pullup resistor;
CC
the minimum value of the resistor is determined by the current-sinking capability of the driver.

description (continued)
These devices are fully specified for hot-insertion applications using I and power-up 3-state. The I circuitry
off
off
disables the outputs, preventing damaging current backflow through the devices when they are powered down.
The power-up 3-state circuitry places the outputs in the high-impedance state during power up and power down,
which prevents driver conflict.
The SN54LVTH574 is characterized for operation over the full military temperature range of –55°C to 125°C.
The SN74LVTH574 is characterized for operation from –40°C to 85°C.
