1. General description
The 74LVC16374A and 74LVCH16374A are 16-bit edge-triggered flip-flops featuring
separate D-type inputs with bus hold (74LVCH16374A only) for each flip-flop and 3-state
outputs for bus-oriented applications. It consists of two sections of eight positive
edge-triggered flip-flops. A clock input (nCP) and an output enable (nOE
) are provided for
each octal.
The flip-flops store the state of their individual D-inputs that meet the set-up and hold time
requirements on the LOW-to-HIGH clock (CP) transition.
When pin nOE
is LOW, the contents of the flip-flops are available at the outputs. When pin
nOE
is HIGH, the outputs go to the high-impedance OFF-state. Operation of input nOE
does not affect the state of the flip-flops.
Inputs can be driven from either 3.3 V or 5 V devices. When disabled, up to 5.5 V can be
applied to the outputs. These features allow the use of these devices in mixed 3.3 V and
5 V applications.
Bus hold on data inputs eliminates the need for external pull-up resistors to hold unused
inputs.
