FAQs

What is SN7493AN?

The SN7493AN is a 4-bit binary ripple counter designed by Texas Instruments. It is commonly used in various digital counting and timing applications, such as frequency dividers, time delay circuits, and clock generation.

How Does SN7493AN Work?

The SN7493AN works by sequentially dividing input clock pulses by powers of 2, producing a binary count output. It utilizes a ripple counter architecture, where each bit toggles when the previous bit changes from high to low. This enables the generation of accurate frequency division and time delays.

How Many Pins does SN7493AN have and What are the Functions of the Pinout Configuration?

The SN7493AN is housed in a 14-pin DIP (Dual Inline Package) package. The pinout configuration includes:

CLK, RCO: Clock input and ripple carry output pins.
Q0-Q3: Binary output pins representing the 4-bit count value.
MR: Master reset input pin.
VCC, GND: Power supply and ground pins, respectively.

What are the Pros and Cons of SN7493AN?

Pros:

Simple to Use: Provides basic binary counting functionality for various applications.
Compact Package: The 14-pin DIP package is widely compatible with standard sockets and circuit boards.
Cost-Effective: Offers a cost-effective solution for digital counting and timing functions.

Cons:

Propagation Delay: The ripple counter architecture may introduce propagation delays in the output.
Limited Functionality: May not offer advanced features or programmability compared to more modern counters.

Are There Any Equivalents/Alternatives to SN7493AN for Recommendation?

The CD4020B from Texas Instruments is a 14-stage binary counter with similar functionality.
Alternatives to the SN7493AN include the 74HC4040 from NXP Semiconductors and the 4017B from ON Semiconductor.
