Part Details:

74VHC14 HEX SCHMITT inverter Features High speed: tPD = 5.5ns (typ.) at VCC = 5V Low power dissipation: ICC = 2 µA (Max.) at TA = 25°C Typical hysteresis: Vh = 1V at VCC = 4.5V Power down protection on inputs SO-14 TSSOP14 Symmetrical output impedance: |IOH| = IOL = 8 mA (Min) Balanced propagation delays: tPLH tPHL Operating voltage range: VCC(Opr) = 2V to 5.5V Pin and function compatible with 74 series 14 Improved latch-up immunity Low noise: VOLP = 0.8V (Max.) Description The 74VHC14 is an advanced high-speed CMOS Pin configuration and function are the same as HEX SCHMITT inverter fabricated with sub- those of the 74VHC04 but the 74VHC14 has micron silicon gate and double-layer metal wiring hysteresis. C2MOS technology. This together with its schmitt trigger function The internal circuit is composed of 3 stages allows it to be used on line receivers with slow including buffer output, which enables high noise rise/fall input signals. immunity and stable output. All inputs and outputs are equipped with Power down protection is provided on all inputs protection circuits against static discharge, giving and 0 to 7V can be accepted on inputs with no them 2KV ESD immunity and transient excess regard to the supply voltage. This device can be voltage. used to interface 5V to 3V. Table 1.
