Product Bulletin The Advanced High-Speed CMOS (AHC/AHCT) Logic Family Today’s designers are looking beyond HC (HCMOS) to meet the increasing demand for designs without sacrificing low noise levels or low cost. Many designers are looking to TI’s AHC/AHCT (Advanced High-Speed CMOS logic) to provide a reliable and effortless migration path from HC. Outlining a reliable migration path is not a simple task for a logic supplier. The supplier must focus on the present and future needs of its customers, while still maintaining the successful features of proven technology. With AHC, TI has done just that. AHC is every- Key features • Same low noise as HC (<0.8 V) • Three times the speed of HC Typical propagation delays of 5.4ns (‘244) • One-half the static power consumption of HC (40 µA) • Wide range of special devices (WidebusTM and PicoGate logic) • Five worldwide sources of advanced HCMOS products • SAME MARKET PRICE AS HC thing a designer embraces in HC, PLUS three times the speed, onehalf the static power consumption, and several more product choices. AHC offers WidebusTM versions of its most popular functions, like the A Reliable and Effortless Migration Path for HCMOS Users A Reliable and Effortless Migration Path for HCMOS Users ’16244, ’16373, and ’16245. Also available is a complete line of single-gate devices, PicoGate Logic, ideally suited for board routing simplicity and last-minute design modifications. AHC/AHCT Input and Output Levels AHC is designed with CMOS inputs and CMOS outputs. AHCT is designed with TTL inputs and CMOS outputs. AHC Performance tpd VCC Range (Recommended) typ. max Volp typ.

Please consult individual device data sheets for 3.3-VCC data. AHC/AHCT Widebus TM 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 40µA (half that of HCMOS), AHC Widebus components will allow designers to increase system speeds while lowering the system’s overall power requirements. Additionally, as with all of TI's AHC components, the Widebus devices offer the same low noise found in HCMOS. Packaging Options 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.

These devices, AHC Microgate Logic in the 5-pin SOT-23 and PicoGate Logic in the 5-pin SOT-353, allow designers to place a particular gate function close to related circuitry, shortening and simplifying routes on a board. This simple implementation represents a major advancement over multiplegate devices, which require the routing of multiple etches from distinct partitions on a printed circuit board through one logic device. These single-gate logic devices also allow designers to alter the output of an ASIC without redesign and re-manufacture, effectively extending the life of the device and maximizing design investment.
