description
These 8-bit latches feature 3-state outputs designed specifically for
driving highly capacitive or relatively low-impedance loads. They are
particularly suitable for implementing buffer registers, I/O ports,
bidirectional bus drivers, and working registers. The eight latches of
the F373 are transparent D-type latches. While the latch-enable (LE)
input is high, the Q outputs will follow the data (D) inputs. When the
latch enable is taken low, the Q outputs are latched at the logic
levels set up at the D inputs. A buffered output-enable (OE) 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-impedance state, the outputs neither load nor drive the bus lines
significantly. The high-impedance state and increased drive provide
the capability to drive bus lines without need for interface or pullup
components.
