ADDENDUM No. 8 to JESD8 - STUB SERIES TERMINATED LOGIC FOR 3.3 VOLTS (SSTL_3) A 3.3 V VOLTAGE BASED INTERFACE STANDARD FOR DIGITAL INTEGRATED CIRCUITS |
JESD8-8 | Aug 1996 |
This standard is a result of a major effort by the JC-16 Committee to develop a high performance CMOS-based interface suitable for high speed main memory applications in excess of 125 MHz. Committee(s): JC-16 Free download. Registration or login required. |

ADDENDUM No. 9 to JESD24 - SHORT CIRCUIT WITHSTAND TIME TEST METHOD:Status: ReaffirmedOctober 2002 |
JESD24- 9 | Aug 1992 |
Test method to determine how long a device can survive a short circuit condition with a given drive level. Committee(s): JC-25 Free download. Registration or login required. |

ADDENDUM No. 9B to JESD8 - STUB SERIES TERMINATED LOGIC FOR 2.5 VOLTS (SSTL_2): Includes Errata and Corrected Page 7 as of October 18, 2002. |
JESD8-9B | May 2002 |
This standard defines the input, output specifications and ac test conditions for devices that are designed to operate in the SSTL_2 logic switching range, nominally 0 V to 2.5 V. The standard may be applied to ICs operating with separate VDD and VDDQ supply voltages. This standard has been developed particularly with the objective of providing a relatively simple upgrade path from MOS push-pull interface designs. The standard is particularly intended to improve operation in situations where busses must be isolated from relatively large stubs. Committee(s): JC-16 Free download.

AIR-CONVECTION-COOLED, LIFE TEST ENVIRONMENT FOR LEAD-MOUNTED SEMICONDUCTOR DEVICES:Status: ReaffirmedFebruary 1972, November 2002 |
EIA323 | Mar 1966 |
This standard is applicable to life testing of lead-mounted semiconductor devices intended for applications in a natural air-cooled environment where most of the power dissipation is obtained by convection and radiation losses from the body to the device.

ALPHA RADIATION MEASUREMENT IN ELECTRONIC MATERIALS |
JESD221 | May 2011 |
This standard applies generally to gas proportional instruments and the use thereof in measuring materials with an alpha emissivity of less than 10 a·khr-1·cm-2. The primary focus will be on materials used in semiconductor fabrication. The purpose of this document is to specify the recommended method for measuring alpha emissivity in materials utilized in the manufacturing of semiconductors. The method specifically applies to gas proportional instruments and designates recommended instrument settings. In addition, the method discusses operation of ionization counters. The document also recommends methods for determining sample size and for evaluating instrument background accurately. Free download. Registration or login required. |
