DESCRIPTION
The 74ALVCH16374 is a 16-bit edge-triggered flip-flop featuring
separate D-type inputs for each flip-flop 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. The 74ALVCH16374 consists of 2 sections of eight
edge-triggered flip-flops. A clock (CP) input and an output enable
(OE) are provided per 8-bit section.
The 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.
When OE is LOW, the contents of the flip-flops 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
flip-flops.
