Low−Voltage 1.8/2.5/3.3 V

16−Bit Transparent Latch

With 3.6 V−Tolerant Inputs and Outputs

(3−State, Non−Inverting)

The 74VCXH16373 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.

DT SUFFIX

CASE 1201

When operating at 2.5 V (or 1.8 V) the part is designed to tolerate

voltages it may encounter on either inputs or outputs when interfacing

to 3.3 V busses. It is guaranteed to be overvoltage tolerant to 3.6 V.

The 74VCXH16373 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 pullup resistors to hold unused or

floating inputs at a valid logic state.

*To ensure the outputs activate in the 3−state condition,

the output enable pins should be connected to V through a

pull−up resistor. The value of the resistor is determined by the

current sinking capability of the output connected to the OE pin.
