1 Wide Operating Voltage Range of 2 V to 6 V High-Current 3-State Noninverting Outputs Drive Bus Lines Directly or Up To 5 LSTTL Loads Low Power Consumption, 80-µA Max I CC Typical t pd = 22 ns ±6-mA Output Drive at 5 V Low Input Current of µa Max Bus-Structured Pinout description/ordering information These octal edge-triggered D-type flip-flops feature 3-state outputs designed specifically for bus driving. They are particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers. The eight flip-flops enter data on the low-to-high transition of the clock (CLK) input. 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 lines significantly. The high-impedance state and increased drive provide the capability to drive bus lines without interface or pullup components.
