GROUP SELECT INDICATES ONE OR MORE PRIORITY INPUTS . QUIESCENT CURRENT SPECIFIED TO 20V FOR HCC DEVICE . STANDARDIZED SYMMETRICAL OUTPUT CHARACTERISTICS . 5V, 10V, AND 15V PARAMETRIC RATINGS . INPUT CURRENT OF 100 nA AT 18V AND 25 °C FOR HCC DEVICE . 100% TESTED FOR QUIESCENT CURRENT . MEETS ALL REQUIREMENTS OF JEDEC TEN- TATIVE STANDARD N o 13A, ”STANDARD SPECIFICATIONS FOR DESCRIPTION OF ”B” SERIES CMOS DEVICES” June 1989 The HCC4532B (extended temperature range) and HCF4532B (intermediate temperature range) are monolithic integrated circuit, available in 16-lead dual in-line plastic or ceramic package and plastic micro package. The HCC/HCF4532 consists of combinational logic that encodes the highest priority input (D7-D0) to a 3-bit binary code. The eight inputs, D7 through D0, each have an assigned priority. D7 is the highest priority and D0 is the lowest. The priority encoder is inhibited when the chip-enable input El is low. When El is high, the binary representation of the highest- priority input appears on output lines Q2-Q0, and the group select line GS is high to indicate that priority inputs are present. The enable-out (EO)is high when no priority inputs are present. If any one input is high, EO is low and all cascaded lower-order stages are disabled.
