DESCRIPTION
The 74ALVCH16373 is a 16-bit D-type transparent latch featuring
separate D-type inputs for each latch and 3-State outputs for bus
oriented applications. Incorporates bus hold data inputs which
eliminate the need for external pull-up or pull-down resistors to hold
unused inputs. One latch enable (LE) input and one output enable
(OE) are provided per 8-bit section.
The 74ALVCH16373 consists of 2 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, i.e., a latch output will change each time its
corresponding D-input changes.
When LE is LOW the latches store the information that was present
at the D-inputs a set-up time 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.
