74193 Synchronous 4-Bit Up/Down Binary Counter IC (DIP-16) | Pro Tronix

Product Description

The 74193 Synchronous 4-Bit Up/Down Binary Counter IC is a high-speed TTL logic integrated circuit designed for synchronous counting, frequency division, and programmable digital countdown applications. Featuring separate clock inputs for counting up and counting down, dual borrow and carry outputs for easy cascading, and asynchronous master reset, this versatile counter provides precise binary state tracking for digital systems, frequency counters, and custom timing circuits.

Operating on standard 5V TTL logic levels, it allows asynchronous parallel loading of data through jam inputs, making it an essential component for programmable timers and digital sequencers.

⚠️ Logic & Power Tip: Keep your VCC supply strictly within the standard TTL range of 4.75V to 5.25V DC (5V nominal). Ensure unused clock inputs are held high or low properly to prevent false triggering during active counting cycles.

Technical & Architectural Highlights

• Synchronous 4-Bit Operation: Internal flip-flops trigger synchronously for high-speed counting without ripple delay across bits.

• Dual Clock Inputs: Separate dedicated pins for Up counting and Down counting simplify external control logic.

• Asynchronous Parallel Load: Jam inputs allow instant loading of any 4-bit starting value when the Load pin is pulled low.

• Cascadable Carry & Borrow Outputs: Terminal Count Up and Terminal Count Down outputs enable multi-chip cascading for larger counting capacities.
