TC74HC4049AFTEL

The TC74HC4049AFTEL from Toshiba is a high-speed CMOS hex buffer/converter featuring an inverting logic function. Fabricated with silicon gate C2MOS technology, it achieves high-speed operation comparable to LSTTL while maintaining low CMOS power dissipation. This device is suitable for logic-level conversion from high-level voltages up to 15V to lower-level voltages, making it useful in battery backup circuits.

Key electrical characteristics include a wide operating voltage range of 2.0V to 6.0V and a typical propagation delay of 9 ns at 5.0V. It offers high noise immunity and symmetrical output impedance with a minimum |IOH| = IOL of 6 mA. The buffer operates within a temperature range of -40°C to 85°C.

Packaged in a 16-TSSOP, the TC74HC4049AFTEL is designed for surface mounting. Its internal circuitry provides stable output and high noise immunity. Power-down protection is incorporated on all inputs, enhancing its reliability in various applications.

This inverting buffer is part of Toshiba's HC family, known for balancing speed and low power consumption. Its design facilitates efficient logic level translation and signal buffering in digital systems.
