Texas Instruments Announces Faster Advanced Low-Voltage CMOS 3.3V Logic Devices

DALLAS (Nov. 18, 1996) -- Strengthening its position as the world's leading provider of 3.3V logic solutions, Texas Instruments (TI) announces increased speed in its Advanced Low-Voltage CMOS (ALVC) 3.3V family. TI's highest-performance 3.3V logic family offers an extensive array of product and packaging choices. These specially designed 3.3V devices, processed with TI's 0.6 micron Complementary Metal-Oxide Semiconductor (CMOS) technology, have significantly reduced maximum propagation delays up to 15% and are ideal in applications such as computer workstations and notebook computers.

These faster ALVC devices have bus hold along with current drive of 24mA and static power consumption of 40µA for bus-interface tasks. Some of the devices include innovative functions for memory interleaving, multiplexing, and interfacing to Synchronous Dynamic Random Access Memory (SDRAMs) and series resistors. Many of these functions are available with integrated series damping resistors to reduce signal overshoot and undershoot.

Features/Benefits

Decreased maximum propagation delay	Allows user to design their system to a lower specified propagation delay.

Constant minimum propagation delay with reduced maximum propagation delay	Narrows the best and worst case margin, resulting in greater simplicity in system design.

Bus hold on every device	Eliminates the need for external pull-up resistors.

Broad product offering	Provides designers with more system choices.

Advanced packaging solutions (SSOP and TSSOP)	Gives users packaging alternatives.

End Equipment Applications

Applications for these ALVC devices include:

Computer workstations
Notebook computers
Memory modules
Networking

Devices

The ALVC devices with completed speed improvements are:

Device Name Previous Propagation Delay New Maximum Propagation Delay

ALVCH16244 3.6 ns 3.0 ns

ALVCH16245 3.6 ns 3.0 ns

ALVCH16721 4.9 ns 4.3 ns

ALVCH162827 4.0 ns 3.6 ns

Speed improvements are also planned for the remainder of TI's ALVC family.

Pricing, Packaging and Availability

The ALVC devices, the ALVCH16244, ALVCH16245, ALVCH16721, and ALVCH162827 are available in a shrink small-outline package (SSOP) or a thin shrink small-outline package (TSSOP) and are sampling in a thin very small-outline package (TVSOP) with pricing starting at $1.95 in quantities of 1,000. These devices are now available from Texas Instruments and its authorized distributors.
