ACTIVE: Product device recommended for new designs.
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design.
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.
OBSOLETE: TI has discontinued the production of the device.
(2) Eco Plan -The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) -please check http://www.ti.com/productcontent for the latest availability
information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that
lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes. …

Using High Speed CMOS and Advanced CMOS in Systems With Multiple Vcc
PDF, 43 Kb, Datei veröffentlicht: Apr 1, 1996
Though low power consumption is a feature of CMOS devices sometimes this feature does not meet a designer?s system power supply constraints. Therefore a partial system power down or multiple Vcc supplies are used to meet the needs of the system. This document shows electrostatic discharge protection circuits. It also provides circuit and bus driver examples of partial system power down and curren
