OCTAL D-TYPE EDGE-TRIGGERED FLIP-FLOPS WITH 3-STATE OUTPUTS

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 (CLR) input low. 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 in the high-impedance state. The SN54ALS574B SN54AS574 and SN54AS575 are characterized for operation over the full military temperature range of 55C to 125C. The SN74ALS574B SN74ALS575A SN74AS574 and SN74AS575 are characterized for operation from 0C to 70C. By Texas Instruments
