DESCRIPTION
The 74ALVT16821 high-performance BiCMOS device combines
low static and dynamic power dissipation with high speed and high
output drive. It is designed for V
CC
operation at 2.5V or 3.3V with I/O
compatibility to 5V.
The 74ALVT16821 has two 10-bit, edge triggered registers, with
each register coupled to a 3-State output buffer. The two sections of
each register are controlled independently by the clock (nCP) and
Output Enable (nOE) control gates.
Each register is fully edge triggered. The state of each D input, one
set-up time before the Low-to-High clock transition, is transferred to
the corresponding flip-flop’s Q output.
The 3-State output buffers are designed to drive heavily loaded
3-State buses, MOS memories, or MOS microprocessors.
The active Low Output Enable (nOE) controls all ten 3-State buffers
independent of the register operation. When nOE is Low, the data in
the register appears at the outputs. When nOE is High, the outputs
are in high impedance “off” state, which means they will neither drive
nor load the bus.
