7493 Integrated Circuit FAQs
What is 7493 Integrated Circuit?
7493 IC is a 4-bit binary counter from the 74xx series of TTL (Transistor-Transistor Logic) integrated circuits. It is designed to count in binary from 0 to 15 (0000 to 1111) and is commonly used in digital counting and timing applications.
How many flip-flops does the 7493 IC contain?
The 7493 IC contains four flip-flops internally arranged to count in binary. Each flip-flop represents one bit of the 4-bit binary count.
What are the clock inputs of the 7493 IC?
The 7493 IC has two clock inputs:
- CLK A (Pin 1): Clock input for the first flip-flop (FF1).
- CLK B (Pin 6): Clock input for the divide-by-8 section (FF2, FF3, and FF4).
How does the 7493 IC count?
The 7493 IC counts sequentially from 0 to 15 in binary when triggered by clock pulses applied to CLK A. Each clock pulse increments the count by one.
What are the reset inputs of the 7493 IC?
The 7493 IC has two reset inputs:
- R01 (Pin 2): Reset input 1.
- R02 (Pin 3): Reset input 2. Both reset inputs must be high (logic 1) to reset the counter to 0 (0000).
