SN74ALS874B General Description
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 (CLR) inputs and noninverting Q outputs. The SN74ALS876A and SN74AS876 have preset (PRE) inputs and inverting Q outputs; taking PRE 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 55°C to 125°C. The SN74ALS874B, SN74ALS876A, SN74AS874, and SN74AS876 devices are characterized for operation from 0°C to 70°C.
