Is Now Part of To learn more about ON Semiconductor, please visit our website at www.onsemi.com Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers will need to change in order to meet ON Semiconductor’s system requirements. Since the ON Semiconductor product management systems do not have the ability to manage part nomenclature that utilizes an underscore (_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated device numbers. The most current and up-to-date ordering information can be found at www.onsemi.com. Please email any questions regarding the system integration to Fairchild_questions@onsemi.com.

The circuit features high noise immunity and low power consumption usually associated with CMOS circuitry, yet has speeds comparable to low power Schottky TTL logic. The MM74HC138 has 3 binary select inputs (A, B, and C). If the device is enabled, these inputs determine which one of the eight normally HIGH outputs will go LOW. Two active LOW and one active HIGH enables (G1, G2A and G2B) are provided to ease the cascading of decoders. The decoder’s outputs can drive 10 low power Schottky TTL equivalent loads, and are functionally and pin equivalent to the 74LS138. All inputs are protected from damage due to static discharge by diodes to VCC and ground. Features ■ Typical propagation delay: 20 ns ■ Wide power supply range: 2V–6V ■ Low quiescent current: 80 µA maximum (74HC Series) ■ Low input current: 1 µA maximum ■ Fanout of 10 LS-TTL loads Ordering Code: Order Number MM74HC138M MM74HC138SJ MM74HC138MTC MM74HC138N Package Number Package Description M16A 16-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-012, 0.150” Narrow M16D 16-Lead Small Outline Package (SOP), EIAJ TYPE II, 5.3mm Wide MTC16 N16E 16-Lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153, 4.4mm Wide 16-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300” Wide Devices also available in Tape and Reel.

The worst case leakage current (IIN, ICC, and IOZ) occur for CMOS at the higher voltage and so the 6.0V values should be used. 3 www.fairchildsemi.com MM74HC138 Absolute Maximum Ratings(Note 2) (Note 3) MM74HC138 AC Electrical Characteristics VCC = 5V, TA = 25°C, CL = 15 pF, tr = tf = 6 ns Symbol tPLH Parameter Conditions Guaranteed Typ Maximum Propagation Limit Units 18 25 ns 28 35 ns 18 25 ns 23 30 ns 18 25 ns Delay, Binary Select to any Output tPHL Maximum Propagation Delay, Binary Select to any Output tPHL, tPLH Maximum Propagation Delay, G1 to any Output tPHL Maximum Propagation Delay G2A or G2B to Output tPLH Maximum Propagation Delay G2A or G2B to Output AC Electrical Characteristics CL = 50 pF, tr = tf = 6 ns (unless otherwise specified) Symbol tPLH tPHL tPHL, tPLH tPHL tPLH tTLH, tTHL CIN Parameter VCC Conditions TA= 25°C Typ TA= −40 to 85°C Units Guaranteed Limits Maximum Propagation 2.0V 75 150 189 ns Delay Binary Select to 4.5V 15 30 38 ns any Output LOW-to-HIGH 6.0V 13 26 32 ns Maximum Propagation 2.0V 100 200 252 ns Delay Binary Select to any 4.5V 20 40 50 ns Output HIGH-to-LOW 6.0V 17 34 43 ns Maximum Propagation 2.0V 75 150 189 ns Delay G1 to any 4.5V 15 30 38 ns Output 6.0V 13 26 32 ns Maximum Propagation 2.0V 82 175 221 ns Delay G2A or G2B to 4.5V 28 35 44 ns Output 6.0V 22 30 37 ns Maximum Propagation 2.0V 75 150 189 ns Delay G2A or G2B to 4.5V 15 30 38 ns Output 6.0V 13 26 32 ns Output Rise and 2.0V 30 75 95 ns Fall Time 4.5V 8 15 19 ns 6.0V 7 13 16 ns 3 10 10 pF Maximum Input Capacitance CPD Power Dissipation (Note 6) 75 Capacitance Note 6: CPD determines the no load dynamic power consumption, PD = CPD VCC2f + ICC VCC, and the no load dynamic current consumption, IS = CPD VCC f + I CC. www.fairchildsemi.com 4 pF MM74HC138 Physical Dimensions inches (millimeters) unless otherwise noted 16-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-012, 0.150” Narrow Package Number M16A 16-Lead Small Outline Package (SOP), EIAJ TYPE II, 5.3mm Wide Package Number M16D 5 www.fairchildsemi.com MM74HC138 Physical Dimensions inches (millimeters) unless otherwise noted (Continued) 16-Lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153, 4.4mm Wide Package Number MTC16 www.fairchildsemi.com 6 16-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300” Wide Package Number N16E LIFE SUPPORT POLICY FAIRCHILD’S PRODUCTS ARE NOT AUTHORIZED FOR USE AS CRITICAL COMPONENTS IN LIFE SUPPORT DEVICES OR SYSTEMS WITHOUT THE EXPRESS WRITTEN APPROVAL OF THE PRESIDENT OF FAIRCHILD SEMICONDUCTOR CORPORATION.
