Working Principles

The TC74VHC393FT(EL,M) is a dual 4-bit binary counter that operates based on the clock input signals. Each counter has an individual clock input (CP1, CP2, CP3) and a master reset input (MR1, MR2, MR3). The outputs (Q1, Q2, Q3) can be used as flip-flops or connected to external circuitry as counters.

When a clock pulse is applied to the respective clock input, the counter increments its value by one. The master reset input asynchronously resets the counter to its initial state when activated. This allows for flexible control over the counting sequence.

Detailed Application Field Plans

The TC74VHC393FT(EL,M) is commonly used in various digital logic applications, including but not limited to:

  1. Frequency Division: The counter can be used to divide the frequency of an input signal by powers of two, enabling frequency scaling.
  2. Event Counting: By connecting external circuitry to the counter outputs, it can be used to count events or pulses.
  3. Sequence Generation: The counter outputs can be used to generate specific sequences required in digital systems.
  4. Address Decoding: The counter outputs can be used to decode specific addresses in memory or peripheral devices.

Detailed and Complete Alternative Models

  1. CD74HC393E: 4-bit binary counter with similar functionality, available in DIP-14 package.
  2. SN74LS393N: Dual 4-bit binary ripple counter with asynchronous reset, available in DIP-14 package.
  3. MC74VHC393DR2G: Dual 4-bit binary counter with similar characteristics, available in SOIC-14 package.
