Revised February 1999 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. Typical propagation delay: 13 ns 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. Wide power supply range: 2-6V Low quiescent current: 20 A maximum (74HC Series) Low input current: 1 A maximum Fanout of 10 LS-TTL loads Typical hysteresis voltage: 0.9V at VCC = 4.5V Ordering Code: Order Number MM74HC14M MM74HC14SJ MM74HC14MTC MM74HC14N Package Number M14A M14D MTC14 N14A Package Description 14-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-120, 0.150" Narrow 14-Lead Small Outline Package (SOP), EIAJ TYPE II, 5.3mm Wide 14-Lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153, 4.4mm Wide 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 = 25C, CL = 15 pF, tr = tf = 6 ns Symbol tPHL, tPLH Parameter Conditions Maximum Propagation Delay Typ Guaranteed Limit Units 12 22 ns AC Electrical Characteristics VCC = 2.0V to 6.0V, CL = 50 pF, tr = tf = 6 ns (unless otherwise specified) Symbol Parameter Conditions tPHL, tPLH Maximum Propagation Delay tTLH, tTHL Maximum Output Rise and Fall Time CPD Power Dissipation VCC TA = 25C Typ TA = -40 to 85C TA = -55 to 125C Units Guaranteed Limits 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 6.0V 7 13 16 19 (per gate) 27 ns pF Capacitance (Note 5) CIN Maximum Input Capacitance 5 10 10 10 pF Note 5: CPD determines the no load dynamic power consumption, PD = CPD VCC2 f + ICC VCC, and the no load dynamic current consumption, IS = CPD VCC f + ICC.
