Part Details:

HCF4028B BCD TO DECIMAL DECODER s BCD TO DECIMAL DECODING OR BINARY TO OCTAL DECODING s HIGH DECODED OUTPUT DRIVE CAPABILITY s "POSITIVE LOGIC" INPUTS AND OUTPUTS:DECODED OUTPUTS GO HIGH ON SELECTION DIP SOP s MEDIUM SPEED OPERATION : tPHL, tPLH = 80ns (Typ.) at VDD = 10V s QUIESCENT CURRENT SPECIF. UP TO 20V ORDER CODES s STANDARDIZED SYMMETRICAL OUTPUT PACKAGE TUBE T & R CHARACTERISTICS DIP HCF4028BEY s INPUT LEAKAGE CURRENT I SOP HCF4028BM1 HCF4028M013TR I = 100nA (MAX) AT VDD = 18V TA = 25°C s 100% TESTED FOR QUIESCENT CURRENT s MEETS ALL REQUIREMENTS OF JEDEC JESD13B "STANDARD SPECIFICATIONS inputs, decoding logic gates, and 10 output FOR DESCRIPTION OF B SERIES CMOS buffers. DEVICES" A BCD code applied to the four inputs, A to D,results in a high level at the selected one of 10 DESCRIPTION decimal decoded outputs. Similarly, a 3-bit binary HCF4028B is a monolithic integrated circuit code applied to inputs A through C is decoded in fabricated in Metal Oxide Semiconductor octal code at output 0 to 7 if D = "0". High drive technology available in DIP and SOP packages. capability is provided at all outputs to enhance dc HCF4028B is a BCD to DECIMAL or BINARY to and dynamic performance in high fan-out OCTAL decoder consisting of buffering on all 4 applications.
