资 源 简 介

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.
