10、 TOLERANT INPUTS AND OUTPUTS (From JEDEC Board Ballot JCB-98-43, formulated under the cognizance of the JC-40 Committee on Digital Logic.) 1 Purpose The purpose is to provide a standard for 2.5 V nominal supply voltage logic devices, for uniformity, multiplicity of sources, elimination of confusion,
11、 ease of device specification, and ease of use, thus providing compatibility between devices operating between 2.3 V and 2.7 V supply voltages, as well as overvoltage tolerance with devices operating at 3.3 V, or 5 volts. 2 Scope This standard defines dc interface parameters and test loading for dig
12、ital logic devices based on 2.5 V (nominal) power supply levels. 3 Terms and definitions prefixes: Prefixes “54“ or “74“ immediately preceding family name indicate the operating temperature range. For example, 54xxx refers to Miiitary (MIL) version of devices that are specified over the temperature
13、range of -55 “C to +125 OC. 74xxx refers to the Commercial (COML) version of devices that are specified over -40 OC to +85 OC.
