74LS93 5V 4 Bit Binary Counter 14 Pin DIP

74LS93 5V 4 Bit Binary Counter 14 Pin DIP

The 74LS93 is a 4-bit binary ripple counter IC belonging to the 74LS TTL logic family.
It is capable of counting from 0 to 15 (binary 0000 to 1111) and can be configured for divide-by-2, divide-by-8, or divide-by-16 operations depending on the connections.

Internally, it consists of four JK flip-flops connected in a ripple arrangement.
The first flip-flop (A) is triggered by the input clock pulse, and each subsequent flip-flop toggles on the falling edge of the previous stage output.

The IC operates at +5V and provides TTL-compatible logic levels. It’s widely used in digital counters, timers, frequency dividers, and event counting circuits.

Features

• 4-bit binary ripple counter
• Operating voltage: 4.75V – 5.25V (typical 5V)
• Internal JK flip-flop stages
• Asynchronous Clear and Reset inputs
• Divide-by-2, divide-by-8, or divide-by-16 configurations possible
• Output frequency is clock input ÷ 2ⁿ (n = number of stages)
• Typical propagation delay: 20 ns
• Low power consumption (Schottky TTL technology)
• Package: 14-pin Dual Inline Package (DIP-14)

Functional Description

The 74LS93 consists of two sections:

1. A divide-by-2 flip-flop (connected to CLK A)
2. A divide-by-8 counter (connected to CLK B)

By connecting output A to CLK B, the IC functions as a 4-bit divide-by-16 counter (0–15).
Otherwise, each section can operate independently.

Applications

• Frequency dividers
• Digital clocks and timers
• Event counting and pulse counting
• Time-delay generation
• Binary and decade counters
• LED sequence and light chasers
• Frequency measurement circuits
