description
The ’LV574A devices are octal edge-triggered
D-type flip-flops designed for 2-V to 5.5-V VCC
operation.
These devices feature 3-state outputs designed
specifically for driving highly capacitive or
relatively low-impedance loads. The devices are
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.
To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
The SN54LV574A is characterized for operation over the full military temperature range of –55
°C to 125°C.
The SN74LV574A is characterized for operation from –40
°C to 85°C.
