TC74VHC14F/FN/FT/FK2007-10-011TOSHIBA CMOS Digital Integrated Circuit Silicon MonolithicTC74VHC14F,TC74VHC14FN,TC74VHC14FT,TC74VHC14FKHex Schmitt InverterThe TC74VHC14 is an advanced high speed CMOS SCHMITTINVERTER fabricated with silicon gate C2MOS technology.It achieves the high speed operation similar to equivalentBipolar Schottky TTL while maintaining the CMOS low powerdissipation.Pin configuration and function are the same as theTC74VHC04 but the inputs have hysteresis and with its schmitttrigger function, the TC74VHC14 can be used as a line receiverswhich will receive slow input signals.An input protection circuit ensures that 0 to 5.5 V can beapplied to the input pins without regard to the supply voltage.This device can be used to interface 5 V to 3 V systems and twosupply systems such as battery back up. This circuit preventsdevice destruction due to mismatched supply and input voltages.Features• High speed: tpd = 5.5 ns (typ.) at VCC = 5 V• Low power dissipation: ICC = 2 μA (max) at Ta = 25°C• Power down protection is provided on all inputs.• Balanced propagation delays: tpLH ∼− tpHL• Wide operating voltage range: VCC (opr) = 2 V to 5.5 V• Low noise: VOLP = 0.8 V (max)• Pin and function compatible with 74ALS14WeightSOP14-P-300-1.27A: 0.18 g (typ.)SOL14-P-150-1.27: 0.12 g (typ.)TSSOP14-P-0044-0.65A: 0.06 g (typ.)VSSOP14-P-0030-0.50: 0.02 g (typ.)Note: xxxFN (JEDEC SOP) is not available inJapan.TC74VHC14FTC74VHC14FNTC74VHC14FTTC74VHC14FK
