Flip Flop D-Type Bus Interface Pos-Edge 3-ST 1-Element 20-Pin PDIP Tube
Manufacturer Part #: SN74ABT534ANE4
Avnet Manufacturer Part #: SN74ABT534ANE4
These 8-bit flip-flops with 3-state outputs are designed specifically for driving highly capacitive or relatively low-impedance loads. They are particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers.
The eight flip-flops are edge-triggered D-type flip-flops. On the positive transition of the clock (CLK), the Q\ outputs are set to the complement of 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.
