10、59JEDEC Standard No. 74Page 1DESCRIPTION OF 1.8 V CMOS LOGIC DEVICES(From JEDEC Board Ballot JCB-99-52, formulated under the cognizance of the JC-40 Committee onDigital Logic.)1 PurposeThe purpose is to provide a standard specification for uniformity, multiplicity of sources, elimination ofconfusion

11、, ease of device specification, and ease of use.2 ScopeThis standard defines dc interface, switching parameters and test loading for digital logic devices basedon 1.8 V (nominal) power supply levels.3 Definitions for the purpose of this documentPrefixes “54” or “74” immediately preceding family name

12、 indicate the operating temperature range. Forexample, 54xxx refers to the Military (MIL) version of devices which are specified over temperaturerange of 55 C to +125 C. 74xxx refers to the Commercial (COML) version of devices which arespecified over 40 C to +85 C.4 Standard specifications4.1 Absolu
