DESCRIPTION
The 74VHCT14A is an advanced high-speed CMOS HEX SCHMITT INVERTER fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS technology.
The internal circuit is composed of 3 stages including buffer output, which enable high noise immunity and stable output.
Power down protection is provided on all inputs and outputs 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.
â HIGH SPEED: tPD = 4 ns (TYP.) at VCC = 5V
â LOW POWER DISSIPATION: ICC =2 µA (MAX.) at TA = 25 °C
â TYPICAL HYSTERESIS:0.7V at VCC = 4.5V
â POWERDOWN PROTECTIONON INPUTS & OUTPUTS
â SYMMETRICAL OUTPUT IMPEDANCE: |IOH| = IOL = 8 mA (MIN)
â BALANCEDPROPAGATIONDELAYS: tPLH â
tPHL
â OPERATING VOLTAGERANGE: VCC (OPR)= 4.5V to 5.5V
â PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 14
â IMPROVED LATCH-UP IMMUNITY
â LOW NOISE: VOLP = 0.8V(Max.)
