CD4503 Descripton

CD4503 is a hex non-inverting buffer with three-state outputs that can handle a lot of sinks and source current. In 16-lead hermetic dual-in-line ceramic packaging, the CD4503 Hex buffer is available. This  IC  family offers a variety of functions, including ESD protection and thermal overload protection. In DLD design and logic switching applications, the Hex Buffer CD4503 is critical.

CD4503 Feature

■ Wide supply voltage range: 3.0 VDC to 18 VDC

■ 3-STATE outputs 

■ Symmetrical turn on/turn off delays 

■ Symmetrical output rise and fall times 

■ Pin-for-pin replacement for MM80C97 and MC14503

CD4503 Application

  • 3-State hex buffer for interfacing IC'S with data buses

  • CMOS to TTL Hex Buffer

  • Hex Buffers are also used to isolate other gates or circuit stages from each other preventing the impedance of one circuit from affecting the impedance of another

Frequently Asked Questions

What is A Hex Buffer?
A buffer is a simple logic gate that sends its input to its output unmodified. It behaves in the opposite way that a NOT gate does. The primary function of a buffer is to regenerate the input signal, which is commonly accomplished by utilizing a strong high and a strong low. A buffer has only one input and output, and its output is always the same as its input. Buffers are also utilized to drive huge capacitive loads, which increases the propagation delay of circuits.
What is a hex buffer used for?
These hex buffers and drivers feature high-voltage open-collector outputs to interface with high-level circuits or for driving high-current loads. They are also characterized for use as buffers for driving TTL inputs.
What is the difference between buffer and inverter?
An inverter is a logic gate whose output (X) is the inverse of its input (A). A buffer is a type of logic gate that is used to increase drive capability in order to increase the number of fanouts or the signal speed. A buffer does not perform any logical operation. It also helps shape the waveform of a signal.
