The SLP74LVC16373A device is a 16-bit transparent D-type latch which is designed for 1.2V to 3.6V VCC operation. One Latch Enable (LE) input and one Output Enable (OE(———) are provided for each octal. Inputs can be driven from either 3.3V or 5V devices. When disabled, up to 5.5 V can be applied to the outputs. These features allow the use of these devices in mixed 3.3V and 5V applications.

The device consists of two sections of eight D-type transparent latches with 3-state true outputs. When LE is HIGH, data at the Dn inputs enter the latches. In this condition, the latches are transparent, that is, the latch outputs change each time its corresponding D-input changes. The latches store the information that was present at the D-inputs one set-up time (tsu) preceding the HIGH-to-LOW transition of LE. When OE(——— is LOW, the contents of the eight latches are available at the outputs. When OE——— is HIGH, the outputs go to the high impedance OFF-state. Operation of the OE——— input does not affect the state of the latches.
