Function : 2.5 V / 3.3 V 16-bit D-type transparent latch (3-State)
Производитель : Philips Electronics
The 74ALVCH16373 is 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 nDn inputs enter the latches. In this condition
the latches are transparent, therefore a latch output will changeeach time its
corresponding D-input changes.
When LE is LOW, the latches store the information that was present at the nDn inputs at a
set-up time preceding the LOW-to-HIGH transition of LE. When OEis LOW, the contents
of the eight latches are available at the outputs. When OEis HIGH, the outputs go to the
high-impedance OFF-state. Operation of the OEinput does not affect the state of the
