These 8-bit Flip-Flops feature 3-state outputs 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 of the HC534 are edge-triggered D-type Flip-Flops On the positive transition of the Clock (CLK) input, the Q outputs are set to the complement of the Logic states that were set up at the data (D) inputs. The HC534 are functionally equivalent to the HC374 but the HC534 have inverted outputs. An output-enable (OE) input places 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 lines significantly. The high-impedance state and increased drive provide the capability to drive bus lines without Interface or pullup components. OE does not affect the internal operations of the Flip-Flops Old data CAN be retained or new data CAN be entered while the outputs are off. The SN54HC534 is characterized for operation over the full military temperature range of 55C to 125C. The SN74HC534 is characterized for operation from 40C to 85C By Texas Instruments
