November 1992Revised February 200574VHC04 Hex Inverter74VHC04Hex InverterGeneral DescriptionThe VHC04 is an advanced high speed CMOS Inverterfabricated with silicon gate CMOS technology. It achievesthe high speed operation similar to equivalent BipolarSchottky TTL while maintaining the CMOS low power dissi-pation.The internal circuit is composed of 3 stages including bufferoutput, which provide high noise immunity and stable out-put. An input protection circuit ensures that 0V to 7V can beapplied to the input pins without regard to the supply volt-age. This device can be used to interface 5V to 3V systemsand two supply systems such as battery back up. This cir-cuit prevents device destruction due to mismatched supplyand input voltages.Features High Speed: tPD 3.8 ns (typ) at V CC 5V High noise immunity: V NIH VNIL 28% V CC (Min) Power down protection is provided on all inputs Low Noise: V OLP 0.4V (typ) Low power dissipation: ICC 2 PA (Max) @ T A 25qC Pin and function compatible with 74HC04Ordering Code:Surface mount packages are also available on Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.Pb-Free package per JEDEC J-STD-020B.Note 1: “_NL” indicates Pb-Free package (per JEDEC J-STD-020B).
