The HCF4556B is a dual 1 of 4 decoder/ demultiplexer. Each decoder has two select inputs (A and B), an Enable input (E), and four mutually ) (s t c u ) s ( ct DIP SOP PACKAGE TUBE t e l o DIP SOP u d o r P e ORDER CODES HCF4556BEY HCF4556BM1 T&R HCF4556M013TR s b O exclusive outputs. On the HCF4556B the outputs are low on select. When the Enable input is high, the outputs is high regardless of the state of the select inputs A and B. d o r P e t e l o s b O PIN CONNECTION September 2001 1/9 HCF4556B IINPUT EQUIVALENT CIRCUIT PIN DESCRIPTION PIN No SYMBOL NAME AND FUNCTION 2, 3 1 4, 5, 6, 7 14, 13 15 12, 11, 10, 9 Select Inputs (1/2 of dual) Enable Input (1/2 of dual) Outputs (1/2 of dual) Select Inputs (1/2 of dual) Enable Input (1/2 of dual) Outputs (1/2 of dual) 8 A, B E Q0 to Q3 A, B E Q0 to Q3 VSS 16 VDD Negative Supply Voltage Positive Supply Voltage ) s ( ct u d o TRUTH TABLE r P e INPUTS ENABLE SELECT OUTPUTS E B A Q3 Q2 L L L L H L L H H X L H L H X H H H L H let O ) X : Don’t Care FUNCTIONAL DIAGRAM s ( t c u d o r P e t e l o s b O 2/9 o s b H H L H H Q1 Q0 H L H H H L H H H H HCF4556B LOGIC DIAGRAM ) s ( ct u d o r P e t e l o ABSOLUTE MAXIMUM RATINGS Symbol VDD Parameter DC Input Voltage II DC Input Current PD ) (s Supply Voltage VI t c u s b O Value Unit -0.5 to +22 V -0.5 to VDD + 0.5 ± 10 mA V 200 100 mW mW Top Power Dissipation per Package Power Dissipation per Output Transistor Operating Temperature -55 to +125 °C Tstg Storage Temperature -65 to +150 °C od e t e ol Pr Absolute Maximum Ratings are those values beyond which damage to the device may occur.
