Description

The TC74HC193AF is a high-speed CMOS synchronous 4-bit binary up/down counter manufactured by Toshiba Semiconductor and Storage. It's part of the HC (High-speed CMOS) family, offering improved speed and lower power consumption compared to traditional TTL logic.

Applications

  • Digital Counters
  • Frequency Dividers
  • Address Counters
  • Timers
  • Control Systems

Features

  • Synchronous Operation: All flip-flops are clocked simultaneously, ensuring accurate counting.
  • 4-Bit Binary Counter: Counts from 0 to 15 (or vice versa).
  • Up/Down Counting: Can count up or down based on control inputs.
  • Carry and Borrow Outputs: Allows cascading of multiple counters for higher bit counts.
  • Asynchronous Clear Input: Resets the counter to zero regardless of the clock signal.
  • Preset Inputs: Allows setting the counter to a specific value.
  • High-Speed Operation: Offers fast counting speeds due to the CMOS technology.
  • Low Power Consumption: Minimizes power consumption compared to TTL logic.
  • SOP16 Package: Small Outline Package, suitable for surface mounting.

Benefits

  • Precise Counting: Synchronous operation ensures accurate counting in digital systems.
  • Versatile Functionality: Up/down counting and preset capabilities provide flexibility in various applications.
  • Expandable: Carry and borrow outputs allow for cascading multiple counters to create higher bit counters.
  • Easy Resetting: Asynchronous clear input simplifies resetting the counter.
  • High Performance: High-speed operation enables use in demanding applications.
  • Energy Efficient: Low power consumption reduces overall system power requirements.
  • Compact Size: SOP16 package saves valuable board space.

Additional Details

The TC74HC193AF functions as a synchronous up/down counter, meaning all four flip-flops change state simultaneously on the rising edge of the clock pulse. It has separate clock inputs for up and down counting, providing flexibility in controlling the counting direction. The carry and borrow outputs are active low and indicate when the counter has reached its maximum or minimum value, respectively. This allows multiple TC74HC193AFs to be cascaded to create counters with higher bit counts. The asynchronous clear input allows the counter to be reset to zero at any time, regardless of the clock signal. The preset inputs allow the counter to be initialized to a specific value. It's often used where you need to keep track of a number digitally.

The operating voltage for TC74HC193AF typically ranges from 2V to 6V, consult the datasheet for specifics. The device should be handled according to standard CMOS handling procedures to avoid electrostatic discharge damage.
