Beschreibung von SN74AS574
These octal D-type edge-triggered 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. The SN74ALS575A, SN54AS575, and SN74AS575 may
be synchronously cleared by taking the clear (
) input low.
The output-enable (
)
input 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 SN54ALS574B, SN54AS574, and SN54AS575 are characterized for operation over the full military temperature range of -55°C to 125°C. The SN74ALS574B, SN74ALS575A, SN74AS574, and SN74AS575 are characterized for operation from 0°C to 70°C.
