1 / 6 page © 2000 Fairchild Semiconductor Corporation DS006223 www.fairchildsemi.com April 1984 Revised February 2000 DM74ALS534 Octal D-Type Edge-Triggered Flip-Flop with 3-STATE Outputs General Description These 8-bit registers feature totem-pole 3-STATE outputs designed specifically for driving highly-capacitive or rela- tively low-impedance loads. The high-impedance state and increased high-logic-level drive provide these registers with the capability of being connected directly to and driving the bus lines in a bus-organized system without need for inter- face or pull-up components. They are particularly attractive for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers. The eight flip-flops of the DM74ALS534 are edge-triggered inverting D-type flip-flops. On the positive transition of the clock, the Q outputs will be set to the complement of the logic states that were set up at the D inputs. A buffered output control 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-imped- ance state the outputs neither load nor drive the bus lines significantly. The output control does not affect the internal operation of the flip-flops. That is, the old data can be retained or new data can be entered even while the outputs are off.
