MM74HC4049N

The MM74HC4049N from On Semiconductor is a high-speed CMOS buffer designed for logic level translation. It utilizes advanced silicon-gate CMOS technology to convert high-level logic to low-level logic, operating from a low logic supply. For instance, it can convert 0-15V CMOS logic to 0-5V logic when using a 5V supply. The device features a modified input protection structure that allows input voltages to exceed the supply voltage without damage.

Key electrical specifications include a wide power supply range of 2V to 6V and a typical propagation delay of 8 ns. It has a low quiescent supply current of a maximum of 20 μA. The MM74HC4049N can function as a simple buffer or inverter without level translation and offers a fanout of 10 LS-TTL loads.

This component is housed in a 16-lead Plastic Dual-In-Line Package (PDIP) with a 0.300" width, suitable for through-hole mounting. The operating temperature range is -40°C to 85°C (TA). Its pin and functional compatibility with the CD4049BC makes it a versatile choice for various digital logic applications requiring level shifting or buffering.
