description
The ’AHCT574 devices are octal edge-triggered
D-type flip-flops that feature 3-state outputs
designed specifically for driving highly capacitive
or relatively low-impedance loads. These 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 of the data
(D) inputs.
A buffered output-enable (OE) input places the eight outputs in either a normal logic state (high or low) or the
high-impedance state. In the high-impedance state, the outputs neither load nor drive the bus lines significantly.
The high-impedance state and the increased drive provide the capability to drive bus lines without interface or
pullup components.
OE does not affect internal operations of the flip-flop. 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 SN54AHCT574 is characterized for operation over the full military temperature range of –55
°C to 125°C.
The SN74AHCT574 is characterized for operation from –40
°C to 85°C.
