Low-Voltage 16-Bit Transparent Latch with Bus Hold 1.8/2.5/3.3 V (3–State, Non–Inverting)

The 74ALVCH16373 is an advanced performance, non–inverting 16–bit transparent latch. It is designed for very high–speed, very low–power operation in 1.8 V, 2.5 V or 3.3 V systems. The VCXH16373 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.
The 74ALVCH16373 contains 16 D–type latches with 3–state 3.6 V–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.
