? 2005 fairchild semiconductor corporation ds500059 www.fairchildsemi.com september 1983 revised january 2005 mm74hct14 hex inverting schmitt trigger mm74hct14 hex inverting schmitt trigger general description the mm74hct14 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 74hct logic family is functionally and pinout compati- ble with the standard 74ls logic family. all inputs are pro- tected from damage due to static discharge by internal diode clamps to v cc and ground. features typical propagation delay: 13 ns wide power supply range: 2?6v low quiescent current: 10 a maximum low input current: 1 a maximum fanout of 10 ls-ttl loads typical hysteresis voltage: 0.9v at v cc = 4.5v ttl, ls pin-out and input threshold compatible ordering codes: devices also available in tape and reel. specify by appending the suffix letter ? x ? to the ordering code. pb-free package per jedec j-std-020b. connection diagram pin assignments for dip, soic, sop and tssop top view schematic diagram order number package package description number mm74hct14m m14a 14-lead small outline integrated circuit (soic), jedec ms-012, 0.150" narrow mm74hct14mx_nl m14a pb-free 14-lead small outline integrated circuit (soic), jedec ms-012, 0.150" narrow mm74hct14sj m14d pb-free 14-lead small outline package (sop), eiaj type ii, 5.3mm wide mm74hct14mtc mtc14 14-lead thin shrink small outline package (tssop), jedec mo-153, 4.4mm wide mm74hct14n n14a 14-lead plastic dual-in-line package (pdip), jedec ms-001, 0.300" wide

(the v ih value at 5.5v is 3.85v.) the worst case leakage cur- rent (i in , i cc , and i oz ) occur for cmos at the higher voltage and so the 6.0v values should be used. supply voltage (v cc ) ? 0.5 to + 7.0v dc input voltage (v in ) ? 1.5 to v cc + 1.5v dc output voltage (v out ) ? 0.5 to v cc + 0.5v clamp diode current (i ik , i ok ) 20 ma dc output current, per pin (i out ) 25 ma dc v cc or gnd current, per pin (i cc ) 50 ma storage temperature range (t stg ) ? 65 c to + 150 c lead temperature (t l ) (soldering 10 seconds) 260 c min max units supply voltage (v cc )26v dc input or output voltage (v in , v out )0v cc v operating temperature range (t a ) ? 40 + 85 c symbol parameter conditions v cc t a = 25 ct a = ? 40 to 85 c units typ guaranteed limits v t + positive going minimum 4.5v 1.5 1.2 1.2 v threshold voltage 5.5v 1.7 1.4 1.4 v maximum 4.5v 1.5 1.9 1.9 v 5.5v 1.7 2.1 2.1 v v t ? negative going minimum 4.5v 0.9 0.5 0.5 v threshold voltage 5.5v 1.0 0.6 0.6 v maximum 4.5v 0.9 1.2 1.2 v 5.5v 1.0 1.4 1.4 v v h hysteresis voltage minimum 4.5v 0.6 0.4 0.4 v 5.5v 0.7 0.4 0.4 v maximum 4.5v 0.6 1.4 1.4 v 5.5v 0.7 1.5 1.5 v v oh minimum high level v in = v il output voltage |i out | = 20 av cc v cc ? 0.1 v cc ? 0.1 v |i out | = 4.0 ma, v cc = 4.5v 4.2 3.98 3.84 v |i out | = 4.8 ma, v cc = 5.5v 5.2 4.98 4.98 v v ol maximum low level v in = v ih voltage |i out | = 20 a00.10.1v |i out | = 4.0 ma, v cc = 4.5v 0.2 0.26 0.33 v |i out | = 4.8 ma, v cc = 5.5v 0.2 0.26 0.33 v i in maximum input current v in = v cc or gnd 0.1 1.0 a v ih or v il i cc maximum quiescent v in = v cc or gnd 5.5v 1.0 10 a supply current i out = 0 a v in = 2.4v or 0.5v (note 3) 5.5v 2.4 2.4 ma
