Texas Instruments SN74AS874

these dual 4-bit d-type edge-triggered flip-flops feature 3-state outputs designed specifically as bus drivers. they are particularly suitable for implementing buffer registers i/o ports bidirectional bus drivers and working registers. the edge-triggered flip-flops enter data on the low-to-high transition of the clock (clk) input. the sn54als874b sn74als874b and sn74as874 have clear () inputs and noninverting q outputs. the sn74als876a and sn74as876 have preset () inputs and inverting q\ outputs; taking low causes the four q or q\ outputs to go low independently of the clock. the sn54als874b is characterized for operation over the full military temperature range of -55c to 125c. view all in datasheet
