Product data sheet
1. 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 ï¬ip-ï¬op featuring separate D-type inputs for each
ï¬ip-ï¬op and 3-state outputs for bus-oriented applications. A clock input (pin CP) and an
output enable input (pin OE) are common to all ï¬ip-ï¬ops. The ten ï¬ip-ï¬ops 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 ï¬ip-ï¬ops 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 ï¬ip-ï¬ops.
