DESCRIPTION
HCF40147B is a monolithic integrated circuit fabricated in Metal Oxide Semiconductor technology available in DIP and SOP packages.
HCF40147B, encoder CMOS, features priority encoding of the inputs to ensure that only the highest order data line is encoded. Ten data input lines (0-9) are encoded to four line (8, 4, 2, 1) BCDs.

■ ENCODES 10 LINE TO 4 LINE BCD
■ ACTIVE LOW INPUTS AND OUTPUTS
■ STANDARDIZED, SYMMETRICAL OUTPUT CHARACTERIZATION
■ QUIESCENT CURRENT SPECIFIED UP TO 20V
■ 5V, 10V AND 15V PARAMETRIC RATINGS
■ MAXIMUM INPUT CURRENT OF 1 µA AT 18V OVER FULL PACKAGE TEMPERATURE RANGE; 100 nA AT 18 V AND 25°C
■ NOISE MARGIN (FULL PACKAGE TEMPERATURE RANGE): 1V AT VDD =5V, 2V AT VDD =10V, 2.5V AT VDD = 15V
■ INPUT LEAKAGE CURRENT II = 100nA (MAX) AT VDD = 18V TA = 25°C
■ 100% TESTED FOR QUIESCENT CURRENT
■ MEETS ALL REQUIREMENTS OF JEDEC JESD13B "STANDARD SPECIFICATIONS FOR DESCRIPTION OF B SERIES CMOS DEVICES"
