Description

These SN74AS874 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 SN74AS874 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 andinverting Q outputs; taking PRE  low causes the  four Q  or Qoutputs to go low independently of the clock.

The SN54ALS874B is characterized for operation over the full military temperature range of 55°Cto 125°C. The SN74ALS874B, SN74ALS876A,
SN74AS874, and SN74AS876devices are characterized for operation from 0°C to 70°C.
