Product Description

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.
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 in the high-impedance state.
Wide Operating Voltage Range of 2 V to 6 V
High-Current 3-State Noninverting Outputs Drive Bus Lines Directly or Up To 15 LSTTL Loads
Low Power Consumption, 80-µA Max ICC
Typical tpd = 22 ns
±6-mA Output Drive at 5 V
Low Input Current of 1 µA Max
Bus-Structured Pinout
