Revised February 1999 MM74HC151 8-Channel Digital Multiplexer General Description The MM74HC151 high speed Digital multiplexer utilizes advanced silicon-gate CMOS technology. Along with the high noise immunity and low power dissipation of standard CMOS integrated circuits, it possesses the ability to drive 10 LS-TTL loads. The MM74HC151 selects one of the 8 data sources, depending on the address presented on the A, B, and C inputs. It features both true (Y) and complement (W) outputs. The STROBE input must be at a low logic level to enable this multiplexer. A high logic level at the STROBE forces the W output HIGH and the Y output LOW. 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 data select to output Y: 26 ns ■ Wide operating supply voltage range: 2–6V ■ Low input current: 1 µA maximum ■ Low quiescent supply current: 80 µA maximum (74HC) ■ High output drive current: 4 mA minimum Ordering Code: Order Number MM74HC151M MM74HC151SJ MM74HC151MTC MM74HC151N 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 MM74HC151 Absolute Maximum Ratings(Note 1) (Note 2) MM74HC151 AC Electrical Characteristics VCC = 5V, TA = 25°C, CL = 15 pF, tr = tf = 6 ns Symbol tPHL, tPLH Parameter Conditions Guaranteed Typ Maximum Propagation Delay Units Limit 26 35 ns 27 35 ns 22 29 ns 24 32 ns 17 23 ns 16 21 ns A, B or C to Y tPHL, tPLH Maximum Propagation Delay A, B or C to W tPHL, tPLH Maximum Propagation Delay Any D to Y tPHL, tPLH Maximum Propagation Delay any D to W tPHL, tPLH Maximum Propagation Delay Strobe to Y tPHL, tPLH Maximum Propagation Delay Strobe to W AC Electrical Characteristics CL = 50 pF, tr = tf = 6 ns (unless otherwise specified) Symbol tPHL, tPLH tPHL, tPLH tPHL, tPLH tPHL, tPLH tPHL, tPLH tPHL, tPLH tTLH, tTHL CPD Parameter Conditions VCC TA = 25°C Typ TA = −40 to 85°C TA = −55 to 125°C Guaranteed Limits Units Maximum Propagation Delay 2.0V 90 205 256 300 ns A, B or C to Y 4.5V 31 41 51 60 ns ns 6.0V 26 35 44 51 Maximum Propagation Delay 2.0V 95 205 256 300 ns A, B or C to W 4.5V 32 41 51 60 ns ns 6.0V 27 35 44 51 Maximum Propagation Delay 2.0V 70 195 244 283 ns any D to Y 4.5V 27 39 49 57 ns ns 6.0V 23 33 41 48 Maximum Propagation Delay 2.0V 75 185 231 268 ns any D to W 4.5V 29 37 46 54 ns ns 6.0V 25 32 40 46 Maximum Propagation Delay 2.0V 50 140 175 203 ns Strobe to Y 4.5V 21 28 35 41 ns ns 6.0V 18 24 30 35 Maximum Propagation Delay 2.0V 45 127 159 185 ns Strobe to W 4.5V 20 25 32 37 ns 6.0V 17 22 28 32 ns Maximum Output Rise 2.0V 30 75 95 110 ns and Fall Time 4.5V 8 15 19 22 ns 6.0V 7 13 16 19 Power Dissipation (per package) 110 ns pF Capacitance (Note 5) CIN Maximum Input 5 10 10 10 Capacitance 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 MM74HC151 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 MM74HC151 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.
