MC74HC147 Datasheet | Motorola Semiconductor

.. MOTOROLA SEMICONDUCTOR TECHNICAL DATA Decimal-to-BCD Encoder High- Performance Silicon- Gate CMOS The MC74HC147 is identical in pinout to the LS147. The device inputs are patible with standard CMOS outputs; with pullup resistors, they are patible with LSTTL outputs. This device encodes nine active- low data inputs to four active- low BCD Address Outputs, ensuring that only the highest order active data line is encoded. The implied decimal zero condition is encoded when all nine data inputs are at a high level (inactive). - - - - - - Output Drive Capability: 10 LSTTL Loads Outputs Directly Interface to CMOS, NMOS, and TTL Operating Voltage Range: 2 to 6 V Low Input Current: 1 µA High Noise Immunity Characteristic of CMOS Devices In pliance with the Requirements Defined by JEDEC Standard No. 7A - Chip plexity: 136 FETs or 34 Equivalent Gates N SUFFIX PLASTIC PACKAGE CASE 648- 08 16 1 D SUFFIX SOIC PACKAGE CASE 751B- 05 ORDERING INFORMATION MC74HCXXXN MC74HCXXXD Plastic SOIC PIN ASSIGNMENT D4 1 2 3 4 5 6 7 8 16 15 14 13 12 11 10 9 VCC NC A3 D3 D2 D1 D9 A0 LOGIC DIAGRAM D1 D2 D3 DECIMAL DATA INPUTS (ACTIVE- LOW) D4 D5 D6 D7 D8 D9 11 12 13 1 2 3 4 5 10 9 7 6 14 A0 A1 A2 A3 D5 D6 D7 D8 A2 BCD ADDRESS OUTPUTS (ACTIVE- LOW) A1 GND NC = NO CONNECTION FUNCTION TABLE Inputs H H H H H H H H H L H H H H H H H H L X H H H H H H H L X X H H H H H H L X X X H H H H H L X X X X H H H H L X X X X X H H H L X X X X X X H H L X X X X X X X H L X X X X X X X X H H H H H H H H L L Outputs H H H H L L L L H H H H L L H H L L H H H L H L H L H L H L D9 D8 D7 D6 D5 D4 D3 D2 D1 A3 A2 A1 A0 VCC = PIN 16 GND = PIN 8 NO CONNECTION = PIN 15 10/95 © Motorola, Inc. 1995 REV 6 ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎ ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎ ÎÎÎ ÎÎÎÎÎÎÎÎÎÎÎÎÎÎ ÎÎÎÎÎÎ ÎÎÎ ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎ ÎÎÎ ÎÎÎÎÎÎÎÎÎÎÎÎÎÎ ÎÎÎÎÎÎ ÎÎÎ ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎ ÎÎÎ ÎÎÎÎÎÎÎÎÎÎÎÎÎÎ ÎÎÎÎÎÎ ÎÎÎ ÎÎÎ ÎÎÎÎÎÎÎÎÎÎÎÎÎÎ ÎÎÎÎÎÎ ÎÎÎ ÎÎÎ ÎÎÎÎÎÎÎÎÎÎÎÎÎÎ ÎÎÎÎÎÎ ÎÎÎ ÎÎÎ ÎÎÎÎÎÎÎÎÎÎÎÎÎÎ ÎÎÎÎÎÎ ÎÎÎ ÎÎÎ ÎÎÎÎÎÎÎÎÎÎÎÎÎÎ...
