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 ’BCT373 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.
