74ALVT16821

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

3-state

Rev. 03 — 13 June 2005

Product data sheet

1. General description

The 74ALVT16821 high-performance Bipolar Complementary Metal Oxide

Semiconductor (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 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-ﬂops 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.

2. Features

inputs

Live insertion and extraction permitted

Power-up reset

Power-up 3-state

Output capability: +64 mA and

−32

Latch-up protection:

JESD78: exceeds 500 mA

ESD protection:

MIL STD 883, method 3015: exceeds 2000 V

Machine model: exceeds 200 V
