High-Speed, Low-Voltage Logic Family from Texas Instruments is First to Achieve Sub-Two Nanosecond Propagation Delay
Patent-Pending Design Techniques Increase Speed, Reduce Noise
"While many systems are on the verge of making the transition from 3.3V to 2.5V, we're also seeing that bus speeds are increasing beyond 100 MHz.," said Ed Agis, TI's Worldwide Product Marketing Manager for Logic Products. "This creates a real need in the market for next-generation high-speed, low-voltage logic, and these devices are more than 40 percent faster than comparable logic available today. As part of our gates, octals, Widebus™ and Widebus+™ families, these devices give designers an easy migration path to higher performance and lower voltages." TI's next generation logic is called the Advanced Very-low-voltage CMOS (AVC) family. Although optimized for 2.5V systems, AVC logic effectively supports mixed voltage mode systems because it is compatible with 3.3V as well as 1.8V devices. Maintaining High Speeds, Eliminating System Noise The AVC family features TI's Dynamic Output Control (DOC™) circuit that automatically varies the output impedance of the circuit during signal transitions to reduce noise. In essence, the DOC circuitry provides enough current to achieve high signaling speeds, but quickly switches the impedance level to reduce the undershoot and overshoot noise that is often found in high-speed logic. This feature of AVC logic eliminates the need for damping resistors, which are often used in series and sometimes integrated with logic devices to limit electrical noise. Damping resistors reduce the noise, but they also increase the propagation delay by slowing signals as they pass through the circuitry. AVC logic also has a power-off feature, Ioff, which disables outputs from the device to support live or hot insertion of boards into system backplanes. This is of particular importance for telecommunications, networking and other high-availability applications that must remain running while boards are inserted or removed. Pricing and Availability AVC devices are fabricated using TI's advanced EPIC™ (Enhanced Performance Implanted CMOS) process. Packaging options include thin shrink small-outline packages (TSSOP) and thin very small-outline packages (TVSOP). Samples of the first four members of the AVC logic family are expected to be available from Texas Instruments and its authorized distributors early in the fourth quarter of 1998. Part numbers and anticipated resale pricing in quantities of 1,000 are as follows: AVC16244 16-bit buffer $2.92, AVC16245 16-bit transceiver $2.92, AVC16373 16-bit D-type transparent latch $2.92 and AVC16374 16-bit D-type flip-flop $2.92. Military versions of selected AVC functions are also planned.

DALLAS (Sept. 14, 1998) -- Continuing to bring technological innovations to the logic market, Texas Instruments (TI) announces a new logic family that is the industry's first to achieve maximum propagation delays of less than two nanoseconds (ns). Designers of next-generation high-performance workstations, PCs, servers and networking switching equipment will find the new logic particularly useful. Additionally, the family has been optimized for low-power 2.5V systems and features a unique internal circuit that reduces component costs and board space by eliminating the need for discrete damping resistors.
