DESCRIPTION
These octal edge-triggered D-type flip-flops 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 complements 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 the high-impedance state. In the high-impedance state, the
outputs neither load nor drive the bus linessignificantly. 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 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.
The SN54ACT534 is characterized for operation over the full military temperature range of -55°C to 125°C. The SN74ACT534 is characterized for operation from -40°C to 85°C.
