DESCRIPTION The 8263 employs active output structures PIN CONFIGURATIONS The 8263/8264 3-Input, 4-Bit Multiplexer is to effect minimum delays: the 8264 utilizes a gating array whose function is analogous _ bare collector outputs for expansion of input 8263 to that of a 4-pole, 3-position switch. Four terms. bits of digital data are selected from one Of 16 e064 may be expanded by connecting three inputs.
