74LS193 Binary Up/Down Counter with Clear IC (74193) DIP 16 Package

74LS193 Binary Up/Down Counter with Clear IC (74193) DIP 16 Package

The 74LS193 is a 4-bit synchronous binary up/down counter IC from the 74LS TTL logic family.
It is designed to count upward or downward depending on the logic level applied to the UP or DOWN control inputs.

The device features:

• Separate Count Up (CPU) and Count Down (CPD) clock inputs
• Parallel load (PL) for presetting any binary value
• Asynchronous clear (CLR) to reset all outputs to zero
• Terminal count outputs (TCU and TCD) for cascading multiple counters

All operations are synchronous, meaning outputs change simultaneously on the triggering clock edge, ensuring predictable and glitch-free counting.
