The HD74LS293P is a 4-bit binary counter consisting of four master-slave flip-flops and additional gating to provide a divide-by-two counter and a three-stage binary counter for which the count cycle length is divide-by-eight. It has a gated reset line. All inputs are buffered to lower the drive requirements.

Applications:

• Frequency dividers
• Programmable timers
• Digital counters
• Control circuits
• Instrumentation

Features:

• 4-bit binary counter
• Separate divide-by-two and divide-by-eight sections
• Gated reset inputs
• High-speed operation
• Buffered inputs

Benefits:

• Versatile counting capabilities with two independent counters.
• Easy to reset the counter to its initial state.
• Suitable for high-frequency applications.
• Reduced loading on the driving circuits.

Technical Specifications:

The HD74LS293P operates from a 5V supply. Its operating temperature range is 0°C to +70°C. It is provided in a 14-pin DIP package.

Specific parameters include:

• Supply Voltage: 4.75V to 5.25V
• High-Level Output Current: -0.4mA
• Low-Level Output Current: 8mA
• Clock Frequency: Typically up to 35 MHz
