Revised May 2005 MM74HC14 Hex Inverting Schmitt Trigger General Description Features The MM74HC14 utilizes advanced silicon-gate CMOS technology to achieve the low power dissipation and high noise immunity of standard CMOS, as well as the capability to drive 10 LS-TTL loads. The 74HC logic family is functionally and pinout 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. Typical propagation delay: 13 ns Wide power supply range: 2-6V Low quiescent current: 20 PA maximum (74HC Series) Low input current: 1 PA maximum Fanout of 10 LS-TTL loads Typical hysteresis voltage: 0.9V at VCC 4.5V Ordering Code: Order Number Package Package Description Number MM74HC14M M14A 14-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-012, 0.150" Narrow MM74HC14MX_NL M14A Pb-Free 14-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-012, 0.150" Narrow MM74HC14SJ M14D Pb-Free 14-Lead Small Outline Package (SOP), EIAJ TYPE II, 5.3mm Wide MM74HC14MTC MTC14 14-Lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153, 4.4mm Wide MM74HC14MTCX_NL MTC14 Pb-Free 14-Lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153, 4.4mm Wide MM74HC14N N14A 14-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300" Wide MM74HC14N_NL N14A Pb-Free 14-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. www.fairchildsemi.com 2 MM74HC14 AC Electrical Characteristics VCC 5V, TA 25qC, CL Symbol tPHL, tPLH 15 pF, tr tf 6 ns Parameter Conditions Maximum Propagation Delay Typ Guaranteed Limit Units 12 22 ns AC Electrical Characteristics VCC 2.0V to 6.0V, CL Symbol 50 pF, tr Parameter tf 6 ns (unless otherwise specified) Conditions tPHL, tPLH Maximum Propagation Delay tTLH, tTHL Maximum Output Rise and Fall Time VCC Power Dissipation 25qC TA 40 to 85qC TA 55 to 125qC Guaranteed Limits Units 2.0V 60 125 156 188 ns 4.5V 13 25 31 38 ns 6.0V 11 21 26 32 ns 2.0V 30 75 95 110 ns 4.5V 8 15 19 22 ns 7 13 16 19 6.0V CPD TA Typ (per gate) 27 ns pF Capacitance (Note 5) CIN Maximum Input Capacitance Note 5: CPD determines the no load dynamic power consumption, PD IS CPD VCC f ICC. 5 10 10 10 pF CPD VCC2 f ICC VCC, and the no load dynamic current consumption, Typical Performance Characteristics Input Threshold, VT, VT, vs Power Supply Voltage Propagation Delay vs Power Supply 3 www.fairchildsemi.com MM74HC14 Typical Applications Low Power Oscillator Note: The equations assume t1 t2 !! tpd0 tpd1 www.fairchildsemi.com 4 MM74HC14 Physical Dimensions inches (millimeters) unless otherwise noted 14-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-012, 0.150" Narrow Package Number M14A 5 www.fairchildsemi.com MM74HC14 Physical Dimensions inches (millimeters) unless otherwise noted (Continued) Pb-Free 14-Lead Small Outline Package (SOP), EIAJ TYPE II, 5.3mm Wide Package Number M14D www.fairchildsemi.com 6 MM74HC14 Physical Dimensions inches (millimeters) unless otherwise noted (Continued) 14-Lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153, 4.4mm Wide Package Number MTC14 7 www.fairchildsemi.com MM74HC14 Hex Inverting Schmitt Trigger Physical Dimensions inches (millimeters) unless otherwise noted (Continued) 14-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300" Wide Package Number N14A Fairchild does not assume any responsibility for use of any circuitry described, no circuit patent licenses are implied and Fairchild reserves the right at any time without notice to change said circuitry and specifications.
