The MC74VCX16373 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 MC74VCX16373 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.

4. These AC parameters are preliminary and may be modified prior to release. For CL = 50pF, add approximately 300ps to the AC maximum
specification.
5. Skew is defined as the absolute value of the difference between the actual propagation delay for any two separate outputs of the same device.
The specification applies to any outputs switching in the same direction, either HIGH–to–LOW (tOSHL) or LOW–to–HIGH (tOSLH); parameter
guaranteed by design.
