operation.
The ’LV574 feature 3-state outputs designed
specifically for driving highly capacitive or
relatively low-impedance loads. This device is
particularly suitable for implementing buffer
registers, I/O ports, bidirectional bus drivers, and
working registers.
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 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.
The SN74LV574 is available in TI’s shrink small-outline package (DB), which provides the same I/O pin count
and functionality of standard small-outline packages in less than half the printed-circuit-board area.
The SN54LV574 is characterized for operation over the full military temperature range of –55
°
C to 125
°
C. The
SN74LV574 is characterized for operation from –40
°
C to 85
