TI Introduces Industry's First AHC Widebus™ Logic Devices

New Offerings Enhance TI's Leadership Position In Advanced High-Speed CMOS Logic Market

DALLAS (August 18, 1997) -- Moving forward in its strategy of providing a reliable and effortless migration path for high-speed CMOS (HCMOS) users to advanced high-speed CMOS (AHC) logic, Texas Instruments today announced the industry's first AHC Widebus 16-bit bus interface logic devices. The new products complement TI's established AHC product line, providing an industry-leading array of AHC logic ICs with greater performance, less power consumption and reduced noise than equivalent HCMOS solutions. The Widebus components provide designers with new AHC options that can reduce component counts, board space and overall system cost.

"The introduction of the AHC Widebus devices is just another step in TIs effort to make migrating from HCMOS to Advanced HCMOS technology easier," said Hal Speed, Strategic Marketing Manager for TI Logic Products. "With the absence of HCMOS Widebus devices and the growing requirement for increased bit-width devices, AHC Widebus ICs are ideal for new designs or just replacing two eight-bit HCMOS chips."

Enhanced Performance, lower component count

AHC components offer the same or better features than those designers expect in HCMOS, with no penalty in ease of design or price. Like TI's AHC octals and gates, AHC Widebus ICs offer increased performance over two eight-bit HCMOS devices. With typical propagation delay times of 5.4 ns and static power consumption of 40 microamps (half that of HCMOS), AHC Widebus components will allow designers to increase system speeds while lowering the systems overall power requirements.

Additionally, as with all of TIs AHC components, the Widebus devices offer the same low noise found in HCMOS. With multiple power and ground pins distributed throughout, the AHC Widebus devices can lower noise by 20 percent over two equivalent HCMOS octal devices, providing greater signal integrity throughout the system.

Alternate sourcing ensures migration path

An alternate sourcing agreement between TI and the Logic Products Group of Philips Semiconductor helps ensure the availability of AHC products, not only today but also in the future when HCMOS components may be more difficult to obtain. The agreement includes AHC gates and octals.

Alternate sourcing reinforces TI's strategy of providing AHC as a natural migration path from HCMOS, which currently represents about 30 percent of the total available market for logic, according to the industry analyst firm Insight/Onsite. The AHC Widebus introductions represent a new stage in the TI strategy, which began with the introduction of AHC gates and octals in 1995, and Microgate logic in 1996.

Availability, pricing and packaging

The AHC Widebus logic family is designated SN74AHC16xxx. Devices are available now from TI and its authorized distributors. Packaging options include thin small outline packages (TSSOPs) and thin very small outline packages (TVSOPs). Widebus devices are priced at $.97 in quantities of 1,000.
