description/ordering information
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 ’BCT573 devices are transparent D-type latches. While the latch-enable (LE) input is
high, the Q outputs follow the data (D) inputs. When the latch enable is taken low, the Q outputs are latched
at the logic levels that were 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 the 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 interface or pullup components.
To ensure the high-impedance state during power up or power down, OE should be tied to V
CC
through a pullup
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
OE does not affect internal operations of the latches. Old data can be retained or new data can be entered while
the outputs are in the high-impedance state.
