1 / 6 page TLF11617 October 1995 74VHC14 Hex Schmitt Inverter General Description The ’VHC14 is an advanced high speed CMOS Hex Schmitt Inverter fabricated with silicon gate CMOS technology It achieves the high speed operation similar to equivalent Bi- polar Schottky TTL while maintaining the CMOS low power dissipation Pin configuration and function are the same as the VHC04 but the inputs have hysteresis between the positive-going and negative-going input thresholds which are capable of transforming slowly changing input signals into sharply defined jitter-free output signals thus providing greater noise margin than conventional inverters An input protection circuit ensures that 0V to 7V can be applied to the input pins without regard to the supply volt- age This device can be used to interface 5V to 3V systems and two supply systems such as battery back up This circuit prevents device destruction due to mismatched supply and input voltages Features Y Low power dissipation ICC e 2 mA (Max) at TA e 25 C Y High noise immunity VNIH e VNIL e 28% VCC (Min) Y All inputs are equipped with a power down protection function Y Balanced propagation delays TPLH j TPHL Y Low noise VOLP e 08V (Max) Y Pin and function compatible with 74HC14 Commercial Package Package Description Number 74VHC14M M14A 14-Lead Molded JEDEC SOIC 74VHC14SJ M14D 14-Lead Molded EIAJ SOIC 74VHC14MSC MSC14 14-Lead Molded EIAJ Type 1 SSOP 74VHC14MTC MTC14 14-Lead Molded JEDEC Type 1 TSSOP 74VHC14N N14A 14-Lead Molded DIP Note Surface mount packages are also available on Tape and Reel Specify by appending the suffix letter ‘‘X’’ to the ordering code EIAJ Type 1 SSOP available on Tape and Reel only order MSCX Logic Symbol IEEEIEC TLF11617 – 1 Truth Table A-Inputs Y-Outputs LH HL Connection Diagram Pin Assignment for DIP SSOP TSSOP and SOIC TLF11617 – 2 C1995 National Semiconductor Corporation RRD-B30M125Printed in U S A |
