The TC74VHC393FT(EL,K) is a high-speed, dual 4-bit binary counter manufactured by Toshiba Semiconductor and Storage. This integrated circuit consists of two independent 4-bit binary counters with individual clock, reset, and output pins. It is designed for high-performance applications requiring frequency division, counting, or timing control.

Applications:

• Frequency Dividers: Used to divide input clock frequencies into lower frequencies.
• Timers: Employed in timing circuits for controlling the duration of events.
• Counters: Used in digital counting applications, such as event counters or sequence generators.
• Digital Clocks: Integrated into digital clock circuits for timekeeping functions.
• Control Systems: Used in various control systems for sequencing and timing control.

Features:

• Dual 4-Bit Binary Counter: Contains two independent 4-bit binary counters.
• High-Speed Operation: Operates at high clock frequencies (typically up to 125 MHz).
• Individual Clock and Reset Inputs: Provides independent control over each counter.
• CMOS Technology: Utilizes CMOS technology for low power consumption.
• Small Package: Available in a TSSOP package for space-saving designs.

Benefits:

• Versatile Functionality: Can be used for a wide range of counting, timing, and frequency division applications.
• High-Speed Performance: Enables fast counting and timing operations.

Additional Details:

The TC74VHC393FT(EL,K) counter operates by incrementing its output value on each rising edge of the clock input. The reset input, when asserted, clears the counter to zero. Each counter has four output pins (QA, QB, QC, QD) representing the binary count value. The device operates over a wide voltage range, typically from 2V to 5.5V. The operating temperature range is generally from -40°C to +85°C. The TSSOP (Thin Shrink Small Outline Package) is a surface-mount package that provides good thermal performance and is suitable for automated assembly. The '(EL,K)' suffix usually indicates tape and reel packaging. This counter is an essential component for various digital systems requiring accurate counting and timing functions.
