CD4009 Hex Buffer – Datasheet

5,762 views

CD4009 Hex Buffer/Converter may be used as a CMOS to TTL or DTL logic-level converter or a CMOS high sink-current driver. The IC offers a wide variety of working conditions and voltages and interfaces directly with TTL, CMOS, and NMOS devices. The CD4009UB and CD4010B types are supplied in 16-lead hermetic dual-in-line ceramic packages. CD4009 offers many different features such as ESD protection & thermal overload protection.

What is a Buffer?

A Hex buffer is a basic logic gate that passes its input, unchanged, to its output. Its behavior is the opposite of a NOT gate. The main purpose of a buffer is to regenerate the input, usually using a strong high and a strong low. A buffer has one input and one output; its output is always equal to its input. Buffers are also used to increase the propagation delay of circuits by driving the large capacitive loads.
