The M74LS293P is a 4-bit binary counter, comprised of four master-slave flip-flops internally interconnected to provide either a divide-by-two counter and a divide-by-eight counter or a single divide-by-sixteen counter. It features individual clock inputs for each counter section, allowing for flexible counting configurations. It is designed for a wide range of digital counting applications, including frequency division, timing circuits, and event counters.

Applications:

• Frequency division
• Timing circuits
• Event counters
• Digital clocks
• Programmable timers

Features:

• 4-Bit Binary Counter
• Individual Clock Inputs
• Divide-by-Two and Divide-by-Eight Counters
• Asynchronous Master Reset
• Low Power Consumption

Benefits:

• Flexible Counting Configurations: Can be used as separate divide-by-two and divide-by-eight counters or as a single divide-by-sixteen counter.
• Precise Frequency Division: Provides accurate frequency division for timing and clock applications.
• Simplified System Design: Integrated asynchronous master reset simplifies initialization and error recovery.
• Reduced Power Consumption: Low power Schottky technology minimizes power usage.
• Versatile Application: Suitable for a wide range of counting and timing applications.

Additional Details:

The M74LS293P operates within a supply voltage range of 4.75V to 5.25V and is characterized for operation from 0°C to 70°C. It is housed in a 14-pin DIP package. The device includes two clock inputs (CP0 and CP1), four output pins (QA, QB, QC, and QD), and a master reset input (MR). The outputs change state on the negative-going edge of the clock pulse. A high level on the master reset input resets all outputs to a low logic level.
