74VHC14 Hex Schmitt inverter Datasheet production data Features High speed: t = 5.5 ns (typ.) at V = 5 V PD CC Low power dissipation I = 2 A (max.) at T = 25 C CC A TSSOP14 SO-14 Typical hysteresis: V = 1 V at V = 4.5 V h CC Power-down protection on inputs Symmetrical output impedance Description I = I = 8 mA (min.) OH OL The 74VHC14 device is an advanced high-speed Balanced propagation delay: t t PLH PHL CMOS hex Schmitt inverter manufactured with Operating voltage range sub-micron silicon gate and double-layer metal 2 V (opr.) = 2 V to 5.5 V wiring C MOS technology. The internal circuit is CC composed of 3 stages including a buffer output, Pin and function compatible with 74 series 14 which provides high noise immunity and stable Improved latch-up immunity output. Low noise Power-down protection is provided on all inputs and 0 to 7 V can be accepted on inputs V = 0.8 V (max.) OLP regardless of the supply voltage. This device can ESD performance be used to interface from 5 V to 3 V. HBM: 2000 V Pin configuration and function are the same as MM: 200 V those of the 74VHC04 device but the 74VHC14 CDM: 1000 V device has hysteresis. This along with its Schmitt trigger function allows the device to be used on line receivers with slow Applications rise/fall input signals. Automotive All inputs and outputs are equipped with protection circuits against static discharge, giving Industrial them 2 kV ESD immunity and transient excess Computer voltage. Consumer Table 1.
