DESCRIPTION

ORDER CODES : HCC40147BF HCF40147BM1 HCF40147BEY HCF40147BC1 F (Ceramic Package) (Micro Package) (Chip Carrier) PIN CONNECTIONS .ENCODES 10 LINE TO 4 LINE BCD .ACTIVE LOW INPUTS AND OUTPUTS .STANDARDIZED, SYMMETRICAL OUTPUT CHARACTERIZATION .100 % TESTED FOR QUIESCENT CURRENT AT 20 V .5V, 10V AND 15V PARAMETRIC RATINGS .MAXIMUM INPUT CURREENT OF 1 µA AT 18V OVER FULL PACKAGE TEMPERATURE RANGE; 100 nA AT 18 V AND 25oC .NOISE MARGIN (FULL PACKAGE TEMPERA- TURE RANGE): 1V AT V DD = 5V, 2V AT VDD = 10V, 2.5V AT VDD = 15V APPLICATIONS: .KEYBOARD ENCODING .10 LINE TO BCD ENCODING .RANGE SELECTION The HCC/HCF40147B CMOS encoder 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) BCD. The highest priority line is line 9. All four output lines are logic 1 (VSS) when all input lines are logic 0. All inputs and outputs are buffered, and each output can drive one TTL Low Power Schottky load. The HCC/HCFF40147 is functionally similar to the T54/T74LS147 if pin 15 is tied low. The HCC/HCF40147B types are supplied in 16 lead plastic or ceramic and plastic micropackage.
