74ALVCH16373

Low-Voltage 16-Bit

Transparent Latch with Bus

Hold 1.8/2.5/3.3 V

(3–State, Non–Inverting)

MARKING DIAGRAM

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.

AWLYYWW

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.

Substantially Reduces System Power Requirements

• Latchup Performance Exceeds ±250 mA @ 125°C

• ESD Performance: Human Body Model >2000V; Machine Model >200V

• Second Source to Industry Standard 74ALVCH16373

†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.
