Texas Instruments SN54AS574

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 -55c to 125c. view all in datasheet
