MM74HC157MTCX

Revised February 1999 MM74HC157 Quad 2-Input Multiplexer General Description The MM74HC157 high speed Quad 2-to-1 Line data selector/Multiplexers utilizes advanced silicon-gate CMOS technology. It possesses the high noise immunity and low power consumption of standard CMOS integrated circuits, as well as the ability to drive 10 LS-TTL loads. This device consists of four 2-input digital multiplexers with common select and STROBE inputs. When the STROBE input is at logical “0” the four outputs assume the values as selected from the inputs. When the STROBE input is at a logical “1” the outputs assume logical “0”. The 74HC logic family is functionally as well as pin-out compatible with the standard 74LS logic family. All inputs are protected from damage due to static discharge by internal diode clamps to VCC and ground. Features ■ Typical propagation delay: 14 ns data to any output ■ Wide power supply range: 2–6V ■ Low power supply quiescent current: 80 µA maximum (74HC Series) ■ Fan-out of 10 LS-TTL loads ■ Low input current: 1 µA maximum Ordering Code: Order Number MM74HC157M MM74HC157SJ MM74HC157MTC MM74HC157N 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.

Thus the 4.5V values should be used when designing with this supply. Worst case VIH and VIL occur at VCC = 5.5V and 4.5V respectively. (The VIH value at 5.5V is 3.85V.) 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 MM74HC157 Absolute Maximum Ratings(Note 1) (Note 2) MM74HC157 AC Electrical Characteristics VCC = 5V, TA = 25°C, CL = 15 pF, tr = tf = 6 ns Symbol tPHL, tPLH Parameter Conditions Guaranteed Typ Maximum Propagation Units Limit 14 20 ns 14 20 ns 12 18 ns Delay, Data to Output tPHL, tPLH Maximum Propagation Delay, Select to Output tPHL, tPLH Maximum Propagation Delay, Strobe to Output AC Electrical Characteristics CL = 50 pF, tr = tf = 6 ns (unless otherwise specified) Symbol Parameter Conditions tPHL, tPLH Maximum Propagation Delay, Data to Output VCC TA = 25°C Typ TA = −40 to 85°C TA = −55 to 125°C Guaranteed Limits Units 2.0V 63 125 158 186 ns 4.5V 13 25 32 37 ns ns 6.0V 11 21 27 32 tPHL, tPLH Maximum Propagation 2.0V 63 125 158 186 ns Delay, Select to Output 4.5V 13 25 32 37 ns 6.0V 11 21 27 32 ns tPHL, tPLH Maximum Propagation 2.0V 58 115 145 171 ns Delay, Strobe to Output tTLH, tTHL Maximum Output Rise and Fall Time CIN 4.5V 12 23 29 34 ns 6.0V 10 20 25 29 ns 2.0V 30 75 95 110 ns 4.5V 8 15 19 22 ns 6.0V 7 13 16 19 ns 5 10 10 10 pF Maximum Input Capacitance CPD Power Dissipation (per Capacitance (Note 5) Multiplexer) 57 Note 5: CPD determines the no load dynamic power consumption, PD = CPD VCC2f + ICC VCC, and the no load dynamic current consumption, IS = CPD V CC f + ICC. www.fairchildsemi.com 4 pF MM74HC157 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 MM74HC157 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.
