Supply voltage range of 2.7V to 3.6V
Complies with JEDEC standard no. 8-1A
Inputs accept voltages up to 5.5V
CMOS low power consumption
Direct interface with TTL levels
10-bit positive edge-triggered register
Independent register and 3-State buffer operation
Flow-through pin-out architecture
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 3.3V or 5.0V devices. In 3-state
operation, outputs can handle 5V. This feature allows the use of
these devices as translators in a mixed 3.3V/5V environment.
The 74LVC821A is a10-bit D-type flip-flop featuring separate D-type
inputs for each flip-flop and 3-State outputs for bus-oriented
applications. A clock (CP) and an output enable (OE) input 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 OE is LOW, the contents
of the ten flip-flops is 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.
