Introduction
As the world leader in logic, Texas Instruments (TI) offers
a full spectrum of logic functions and technologies ranging
from the mature bipolar and bipolar complementary
metal-oxide semiconductor (BiCMOS) families to the latest
advanced CMOS families. TI offers process technologies
with the logic performance and features needed in today’s
electronic markets while maintaining support for traditional
logic products.

The “Resources” section provides additional information
about TI logic families, including a list of technical
literature and an overview of alternate sources for most
logic families.

Logic suppliers have historically focused on speed
and low power as the priorities for product family
improvement. As shown in Figure 1, fast performance
is offered by many new TI product technologies such
as AUC (1.8 V), ALVC (3.3 V) and LV-A (5 V), depending
on operating voltage requirements. Other technologies
such as AUP focus on delivering “best-in-class” low-
power performance.
Some logic families have been in the marketplace
for years, the oldest well into its fourth decade. The
“Logic Migration Overview” section gives logic users
a visual guide to migration from the older to the newer
technologies.
Today’s applications are evolving with greater functionality
and smaller size. TI’s goal is to help designers easily
find the ideal logic technology or function they need. By
offering logic families at every price/performance node
along with benchmark delivery, reliability and worldwide
support, TI maintains a firm commitment to remain in the
market with both leading-edge and mature logic lines.
The “Product Index” section provides a snapshot of TI’s
extensive portfolio by function versus technology. The
“Functional Cross-Reference” section shows the portfolio
by device (type number) versus technology.
The “Packaging and Marking Information” section
shows the wide variety of packaging options offered by
TI. Included are advanced surface-mount packages like
fine-pitch, small-outline ball-grid-array (BGA) packages,
quadflatno-lead(QFN)packagesforgatesandoctals,
and WCSP (NanoFree™) packages for single-, dual-
and triple-gate functions.
