SN74ALS577ADWR

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.
