Overview

DM74ALS874B Dual 4-Bit D-Type Edge-Triggered Flip-Flop with 3-STATE Outputs April 1984 Revised February 2000 DM74ALS874B Dual 4-Bit D-Type Edge-Triggered Flip-Flop with 3-STATE Outputs General Description This dual 4-bit register features totem-pole 3-STATE outputs designed specifically for driving highly-capacitive or relatively low-impedance loads.
The high-impedance state and increased high-logic-level drive provide this register with the capability of being connected directly to and driving the bus lines in a bus-organized system without need for interface or pull-up components.
It is particularly attractive for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers.
The eight flip-flops of the DM74ALS874B are edge-triggered D-type flip-flops.
On the positive transition of the clock, the Q outputs will be set to the logic states that were set up at the D inputs.
A buffered output control input can be used to place the eight outputs in either a ...
