CD4502 Strobed Hex Inverter/Buffer – Datasheet

3,262 views

CD4502 belongs to the family of the CD4000 IC series. CD4502 Strobed Hex Inverter/Buffer, consisting of six inverter/buffers with 3 state outputs. A logic “1” on the OUTPUT DISABLE input produces a high impedance state in all six outputs. This feature permits the common busing of the outputs, thus simplifying system design. A Logic “1” on the INHIBIT input switches all six outputs to logic “0” if the OUTPUT DISABLE input is a logic “0”. The IC also offers features such as high noise immunity and ESD protection. CD4502 is always available in a 16-pin hermetically sealed IC package, allowing it to be easily interfaced with NMOS, CMOS, and TTL devices.

Hex Inverter

A Hex inverter gate inverts the input digital signal.  A hex inverter always has high or logic level 1 output when its input is low or at logic level 0, and a low or logic level 0 output when input is high or at logic level 1.

Hex Buffer

A Hex buffer is a logic gate that passes its input, unchanged, to its output. Its behavior is the opposite of a hex inverter. The main purpose of a buffer is to regenerate the input. 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.
