description/ordering information

The ’AHC374 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 can be used to place 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.

description/ordering information (continued)

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.

T o ensure the high-impedance state during power up or power down, OE

should be tied to V

resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

NOTES: 1. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
