description/ordering information
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 ’HCT374 devices are
edge-triggered D-type flip-flops. On the positive
transition of the clock (CLK) input, the Q outputs
are set to the logic levels that were set up at the
data (D) inputs.
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.
