DESCRIPTION

THIS PLE8P8 IS A 6-BIT TRUE/COMPLEMENT AND CLEAR/SET LOGIC FUNCTIONS.  THE
CONTROL LINES (I1 AND I2) SELECT ONE OF FOUR LOGIC FUNCTIONS FOR THE 6-BIT 
INPUT DATA (D1-D6) AND THE 6-BIT OUTPUT FUNCTION (Y1-Y6).

WHEN I1 IS FALSE (I1=LOW) THE FUNCTION IS INVERT IF I2 IS FALSE (I2=LOW) OR
TRUE IF I2 IS TRUE (I2=HIGH).

WHEN I1 IS TRUE (I1=HIGH) THE FUNCTION IS CLEAR IF I2 IS FALSE (I2=LOW) OR SET
IF I2 IS TRUE (I2=HIGH).

THE PLE8P8 ALSO FEATURES THREE-STATE OUTPUTS WITH TWO ACTIVE LOW OUTPUT ENABLE
CONTROLS (/E1 AND /E2).
