1. General description

The 74HC4049 is a hex inverter with over-voltage tolerant inputs. Inputs are overvoltage tolerant to

15 V. This enables the device to be used in HIGH-to-LOW level shifting applications.

2. Features and benefits

• Wide supply voltage range from 2.0 V to 6.0 V

• Overvoltage tolerant inputs to 15 V

• CMOS low power dissipation

• High noise immunity

• Latch-up performance exceeds 100 mA per JESD 78 Class II Level B

• Complies with JEDEC standards:

• JESD8C (2.7 V to 3.6 V)

• JESD7A (2.0 V to 6.0 V)

• ESD protection:

• • HBM JESD22-A114F exceeds 2000 V

• MM JESD22-A115-A exceeds 200 V

• Specified from -40 °C to +85 °C and from -40 °C to +125 °C
