With 3.6V–Tolerant Inputs and Outputs  
(3–State, Non–Inverting)  
The NL74VCXH16373 is an advanced performance, non–inverting  
16–bit transparent latch. It is designed for very high–speed, very  
low–power operation in 1.8V, 2.5V or 3.3V systems. The VCX16373  
is byte controlled, with each byte functioning identically, but  
independently. Each byte has separate Output Enable and Latch  
Enable inputs. These control pins can be tied together for full 16–bit  
operation.  
When operating at 2.5V (or 1.8V) the part is designed to tolerate  
voltages it may encounter on either inputs or outputs when interfacing  
to 3.3V busses. It is guaranteed to be over–voltage tolerant to 3.6V.  
The NL74VCXH16373 contains 16 D–type latches with 3–state  
3.6V–tolerant outputs. When the Latch Enable (LEn) inputs are  
HIGH, data on the Dn inputs enters the latches. In this condition, the  
latches are transparent, (a latch output will change state each time its D  
input changes). When LE is LOW, the latch stores the information that  
was present on the D inputs a setup time preceding the  
HIGH–to–LOW transition of LE. The 3–state outputs are controlled  
by the Output Enable (OEn) inputs. When OE is LOW, the outputs are  
enabled. When OE is HIGH, the standard outputs are in the high  
impedance state, but this does not interfere with new data entering into  
the latches. The data inputs include active bushold circuitry,  
eliminating the need for external pull–up resistors to hold unused or  
floating inputs at a valid logic state.
