C’MOS DIGITAL INTEGRATED CIRCUIT TC 4 532BP SILICON MONOLITHIC ———— SS TOSHIBA (LOGIC/MENORY) TC4532BP 8-BIT PRIORITY ENCODER TC4532BP is eight bit encoder which detects "H" level of the highest order among eight input signals and outputs the corresponding signal position in binary code. The inputs are eight input signals of DO through D7 and Eqy, and when Eqy is set to "L" level, the encode operation is inhibited making all the outputs at "L" level, 16 The encoded output appears on three signal lines QO 1 through Q2 in binary. Eoyr and Gg are the outputs to indicate the operational mode of encoder and used when ‘P(DIP16-P-300A) the number of bits is to be increased by cascade con- nection, Weight : 1.0g(Typ.)
