DESCRIPTION  
The U74HCT373 is an octal transparent D-type latch with  
3-state outputs, and it has 8 channels.  
TSSOP-20  
When the OE input is low and the LE input is high, the Q  
outputs follow the D inputs. When OE is low and LE is low, the  
Q outputs are latched at the logic levels of the D inputs.  
When the OE input is high, the outputs are in the  
high-impedance. The 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.  
To ensure the high-impedance state during power up or  
power down, OE should be tied to VCC through a pull-up  
resistor; the minimum value of the resistor is determined by the  
current-sinking capability of the driver.
