CD54HC4049F3A Description

Short technical summary and product information.

The CD54HC4049F3A from HAR is a high-speed CMOS logic device featuring a hex buffer/inverter configuration. Fabricated with silicon gate technology, it includes a modified input protection structure that allows it to function as a logic level translator, converting high-level logic signals to low-level logic signals. For example, it can down-convert 15-V input pulse levels to 0-V to 5-V logic levels.

Key electrical specifications include a typical propagation delay of 6ns at 5V supply and 15pF load capacitance. The device operates within a voltage range of 2V to 6V and maintains high noise immunity. It supports a wide operating temperature range from -55°C to 125°C.

This component can be used as simple buffers or inverters without level translation. It offers significant power reduction compared to LSTTL logic ICs. The CD54HC4049F3A is available in a 16-lead CERDIP package, suitable for through-hole mounting.

With standard outputs providing a fanout of 10 LSTTL loads and bus driver outputs offering 15 LSTTL loads, this device is designed for robust performance in various logic applications.
