SN74ALS876A 具有三态输出的双路 4 位 D 类边沿触发器
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 -55°C to 125°C
