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.
These flip-flops enter data on the low-to-high transition of the clock (CLK) input.
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
disabled.
The SN54ALS576B and SN54AS576 are characterized for operation over the full military temperature range of -55°C to 125°C. The SN74ALS576B, SN74ALS577A, and SN74AS576 are characterized for operation from 0°C to 70°C.
