74LS593 8-Bit Binary Counter with an Input Register 5V IC DIP-16
The 74593 is a 74-series digital logic device that combines binary counting with input-register functionality. It is intended for digital systems that need to count clock pulses and handle digital input data within a logic circuit. Its counter and register functions can help simplify designs that would otherwise require separate logic components.
This IC is suitable for digital control circuits, pulse-counting systems, timing applications, and logic experiments. It is supplied in a 16-pin dual in-line package (DIP-16) for through-hole mounting. Since exact functions and pin assignments can vary with the specific device designation and manufacturer, the datasheet should be checked before designing a circuit around a part marked 74593.
Features:
- 8-bit binary counting.
- Integrated parallel input register.
- Separate clock inputs for the counter and input register.
- Three-state parallel outputs.
- Direct counter load and clear functions.
- Counter enable controls.
- Ripple-carry output for cascading counters.
- Suitable for digital bus interfacing.
