TI 公司 逻辑器件 选型手册
As the world leader in logic, Texas Instruments (TI) offers a full spectrum of logic functions and technologies ranging from the mature bipolar and BiCMOS families to the latest advanced CMOS families. TI offers process technologies with the logic performance and features needed in today’s elec- tronic markets while maintaining support for the traditional logic products. TI’s product offerings include the following process technolo- gies or device families: •AC, ACT, AHC, AHCT, ALVC, AUC, AUP, AVC, FCT, HC, HCT, LV-A, LV-AT, LVC, TVC •ABT, ABTE, ALB, ALVT, BCT, HSTL, LVT •BTA, CB3Q, CB3T, CBT, CBT-C, CBTLV, FB, FIFOs, GTL, GTLP, JTAG, I2C, VME •ALS, AS, F, LS, S, TTL Some Logic families have been in the marketplace for years, the oldest well into their fourth decade. The “Logic Migration Overview” section gives logic users a visual guide to migra- tion from the older to the newer technologies. Today’s applications are evolving with greater functionality and smaller size. TI’s goal is to help designers easily find the ideal logic technology or function they need. By offering logic families at every price/performance node along with bench- mark delivery, reliability and worldwide support, TI maintains a firm commitment to remain in the market with both leading- edge and mature logic lines. The “Product Index” section pro- vides a snapshot of TI’s extensive portfolio by function versus technology. The “Functional Cross-Reference” section shows the portfolio by device (type number) versus technology. Logic suppliers have historically focused on speed and low power as the priorities for product family improvement. As shown in Figure 1, fast performance is offered by many new TI product technologies such as AUC (1.8 V), ALVC (3.3 V) and 0 5 10 15 20 25 0 1 2 3 4 5 6 7 CMOS Voltage, VCC (V) Typical Propagation Delay, tpd (ns) HC AHC AC LVA LVC ALVC AVC AUC Figure 1. CMOS Voltage vs. Speed LV-A (5 V), depending on operating voltage requirements. Other technologies such as AUP focus on delivering “best-in- class” low-power performance. The “Packaging and Marking Information” section shows the wide variety of packaging options offered by TI. Included are advanced surface-mount packages like the fine-pitch, small- outline ball-grid-array (BGA) packages, quad flat no-lead (QFN) packages for gates and octals; and WCSP (NanoStar™/ NanoFree™) packages for single-, dual- and triple-gate functions. The new NanoStar/NanoFree WCSP packages are the world’s smallest logic packages, offering a 70% savings in space over industry-standard SC-70 packages. The “Resources” section provides additional information about TI logic families, including a list of technical literature and an overview of alternate sources for most logic families. Data sheets can be downloaded from the TI web site at www.ti.comor ordered through your local sales office or TI authorized distributor. (See back cover.)
