DM74ALS374
Octal 3-STATE D-Type Edge-Triggered Flip-Flop
General Description
This 8-bit register features totem-pole 3-STATE outputs
designed specifically for driving highly-capacitive or rela-
tively low-impedance loads. The high-impedance state and
increased high-logic-level drive provides this register with
the capability of being connected directly to and driving the
bus lines in a bus-organized system without need for inter-
face 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 DM74ALS374 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 normal logic state (HIGH or LOW
logic levels) or a high-impedance state. In the high-imped-
ance state the outputs neither load nor drive the bus lines
significantly.
The output control does not affect the internal operation of
the flip-flops. That is, the old data can be retained or new
data can be entered even while the outputs are OFF.
