DESCRIPTION/ORDERING INFORMATION  
The SN54LVC573A octal transparent D-type latch is designed for 2.7-V to 3.6-V VCC operation, and the  
SN74LVC573A octal transparent D-type latch is designed for 1.65-V to 3.6-V VCC operation.  
These devices feature 3-state outputs designed specifically for driving highly capacitive or relatively  
low-impedance loads. They are particularly suitable for implementing buffer registers, input/output (I/O) ports,  
bidirectional bus drivers, and working registers.  
While the latch-enable (LE) input is high, the Q outputs follow the data (D) inputs. When LE is taken low, the Q  
outputs are latched at the logic levels 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.  
OE does not affect the 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.  
These devices are fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the  
outputs, preventing damaging current backflow through the device when it is powered down.  
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas  
Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
