DESCRIPTION/ORDERING INFORMATION  
The SN54LVC373A octal transparent D-type latch is designed for 2.7-V to 3.6-V VCC operation, and the  
SN74LVC373A octal transparent D-type latch is designed for 1.65-V to 3.6-V VCC operation.  
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 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.  
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 devices when they are powered down.  
To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup  
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.  
Inputs can be driven from either 3.3-V or 5-V devices. This feature allows the use of these devices as translators  
in a mixed 3.3-V/5-V system environment.
