description
These 8-bit registers feature 3-state outputs
designed specifically for driving highly capacitive
or
relatively
low-impedance
loads.
The
high-impedance
3-state
and
increased
high-logic-level drive provide these registers with
the capability of being connected directly to and
driving the bus lines in a bus-organized system
without need for interface or pullup components.
These devices are particularly attractive for
implementing
buffer
registers,
I/O
ports,
bidirectional bus drivers, and working registers.
The eight latches of the ’LS373 and ’S373 are
transparent D-type latches, meaning that while
the enable (C or CLK) input is high, the Q outputs
follow the data (D) inputs. When C or CLK is taken
low, the output is latched at the level of the data
that was set up.
The eight flip-flops of the ’LS374 and ’S374 are
edge-triggered D-type flip-flops. On the positive
transition of the clock, the Q outputs are set to the
logic states that were set up at the D inputs.
Schmitt-trigger buffered inputs at the enable/clock lines of the ’S373 and ’S374 devices simplify system design
as ac and dc noise rejection is improved by typically 400 mV due to the input hysteresis. A buffered
output-control (OC) input can be used to place the eight outputs in either a normal logic state (high or low logic
levels) or the high-impedance state. In the high-impedance state, the outputs neither load nor drive the bus lines
significantly.
OC does not affect the internal operation of the latches or flip-flops. That is, the old data can be retained or new
data can be entered, even while the outputs are off.
