74LVX14 LOW VOLTAGE CMOS HEX SCHMITT INVERTER HIGH SPEED: tPD = 6.8 ns (TYP.) at VCC = 3.3V LOW POWER DISSIPATION: ICC = 2 A (MAX.) at TA = 25 oC LOW NOISE: VOLP = 0.3 V (TYP.) at VCC = 3.3V SYMMETRICAL OUTPUT IMPEDANCE: |IOH| = IOL = 4 mA (MIN) BALANCED PROPAGATION DELAYS: tPLH tPHL OPERATING VOLTAGE RANGE: VCC (OPR) = 2V to 3.6V (1.2V Data Retention) PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 14 IMPROVED LATCH-UP IMMUNITY DESCRIPTION The 74LVX14 is a low voltage CMOS HEX SCHMITT INVERTER fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS technology. It is ideal for low power and low noise 3.3V applications. It has better speed performance at 3.3V than 5V LSTTL family combined with the true CMOS low power consumption. M (Micro Package) T (TSSOP Package) ORDER CODES : 74LVX14M 74LVX14T Pin configuration and function are the same as those of the LVX04 but the LVX14 has histeresys between the positive and negative input threshold typically of 1V. This together with its schmitt trigger function allows it to be used on line receivers with slow rise/fall input signals. Power down protection is provided on all inputs and 0 to 7V can be accepted on inputs with no regard to the supply voltage. This device can be used to interface 5V to 3V. All inputs and outputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage.
