DESCRIPTION
The 74ALVCH16823 is a 18-bit edge-triggered flip-flop featuring
separate D-type inputs for each flip-flop and 3-state outputs for bus
oriented applications. Incorporates bushold data inputs which
eliminate the need for external pull-up resistors to hold unused
inputs. The74ALVCH16823 consists of two sections of nine
edge-triggered flip-flops. A clock (CP) input, an output-enable (OE)
input, a Master reset (MR) input and a clock-enable( CE) input are
provided for each total 9-bit section.
With the clock-enable (CE) input LOW, the D-type flip-flops will store
the state of their individual D-inputs that meet the set-up and hold
time requirements on the LOW-to-HIGH CP transition. Taking CE
HIGH disables the clock buffer, thus latching the outputs. Taking the
Master reset (MR) input LOW causes all the Q outputs to go LOW
independently of the clock.
When OE is LOW, the contents of the flip-flops are available at the
outputs. When the OE is HIGH, the outputs go to the high
impedance OFF-state. Operation of the OE input does not affect the
state of flip-flops.
Active bus hold circuitry is provided to hold unused or floating data
inputs at a valid logic level.
