FK PACKAGE (TOP VIEW) 1Q OE VCC 1D 2D These flip-flops enter data on the low-to-high transition of the clock (CLK) input. The output-enable (OE) 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...
