74ALVT162821

Rev. 4 — 24 January 2018

20-bit bus interface D-type flip-flop; positive-edge trigger with

30 Ω termination resistors; 3-state

Product data sheet

General description

The 74ALVT162821 high-performance BiCMOS device combines low static and dynamic

power dissipation with high speed and high output drive. It is designed for V

operation

at 2.5 V or 3.3 V with I/O compatibility to 5 V.

The 74ALVT162821 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

When nOE is HIGH, the outputs are in high-impedance OFF-state, which means they will

neither drive nor load the bus.

The 74ALVT162821 is designed with 30 Ω series resistance in both HIGH and LOW

output stages. This design reduces the line noise in applications such as memory

address drivers, clock drivers and bus receivers/transmitters. The series termination

resistors reduce overshoot and undershoot and are ideal for driving memory arrays.
