General description

The 74LVC821A is a high performance, low power, low voltage Si-gate CMOS device and superior to most advanced CMOS compatible TTL families.

Inputs can be driven from either 3.3 V or 5 V devices. In 3-state operation, outputs can handle 5 V. This feature allows the use of these devices as translators in a mixed 3.3 V and 5 V environment.

The 74LVC821A is a 10-bit D-type flip-flop featuring separate D-type inputs for each flip-flop and 3-state outputs for bus-oriented applications. A clock input (pin CP) and an output enable input (pin OE) are common to all flip-flops. The ten flip-flops will store the state of their individual D-inputs that meet the set-up and hold times requirements on the LOW-to-HIGH CP transition. When pin OE is LOW, the contents of the ten flip-flops is available at the outputs.

When pin OE is HIGH, the outputs go to the high-impedance OFF-state. Operation of the OE inputs does not affect the state of the flip-flops.
