INTRODUCTION
Since its inception in 1994, the Texas Instruments (TI) ALVC (Advanced Low-Voltage CMOS)
logic family has been the de facto standard for high-performance low-voltage logic. Designed
for operation in the 2.3-V to 3.6-V V
CC
range, the close to 80 functions of the ALVC family allow
the design flexibility and ease needed for today’s most demanding high-performance systems.
For bus-interface functions, ALVC offers a current drive of 24 mA and static power consumption
of 40 µA. Bus-hold cells on the inputs of ALVC devices eliminate the need for external pullup
resistors and prevent inputs from floating.
The ALVC family, which includes innovative functions for memory interleaving, multiplexing, and
interlacing to SDRAMS, has gained prominence in the high-speed memory market. The ALVC
family offers the industry’s most complete line of high-speed memory interface logic devices. A
number of ALVC devices feature series damping resistors for improved noise performance. Also,
a number of devices without bus hold are ideally suited for PC100 applications.
SSTL (Stub Series-Terminated Logic) is the computer industry’s leading choice for
next-generation technology in high-speed memory subsystems, adopted by a JEDEC standard
and endorsed by major memory module, workstation, and personal computer (PC)
manufacturers. Five devices are included in the SSTL section of this data book.
ALB (Advanced Low-Voltage BiCMOS) logic is the fastest BiCMOS logic family available from
TI. With clamping diodes to eliminate undershoot and overshoot, these two 3.3-V Widebus
devices address the high-speed demands of the industry.
HSTL (High-Speed Transceiver Logic) devices accept HSTL-level inputs and produce
LVTTL-level output signals. HSTL devices have found a home in select memory-addressing
applications.
