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 busoriented 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.
