Key Features
- Synchronous 4-bit bidirectional binary counter with separate up/down count control
- 30MHz maximum operating frequency with clocked carry output (TCO) for cascading multiple counters
- 3-state outputs enable bus-sharing in microprocessor and digital control systems
- Load/preset input allows parallel loading of any 4-bit value for flexible initialization
Applications
The SN74ALS569ANE4 is ideal for digital counting and sequencing applications such as frequency dividers, address counters in memory systems, and position encoders in industrial automation. Its bidirectional counting capability and 3-state outputs make it suitable for bus-interfaced systems in embedded controllers and programmable logic applications. The ALS family speed and drive strength fit legacy TTL-compatible designs where 30MHz operation and cascadable carry outputs are required.

Frequently Asked Questions
What is the maximum counting frequency of the SN74ALS569ANE4?
The SN74ALS569ANE4 supports a maximum clock frequency of 30MHz at nominal supply voltage, enabling high-speed synchronous counting in digital systems requiring fast binary accumulation or division.
What does the 3-state output feature provide in the SN74ALS569ANE4?
The 3-state (tri-state) outputs allow the counter's data lines to be placed in a high-impedance state, enabling multiple devices to share a common data bus without signal contention in microprocessor and memory interface designs.
Can the SN74ALS569ANE4 count both up and down?
Yes, the SN74ALS569ANE4 is a bidirectional counter supporting both up and down counting modes. Direction is controlled by a dedicated input, and a clocked carry output (TCO) facilitates cascading for wider counter configurations.
What package does the SN74ALS569ANE4 use?
The SN74ALS569ANE4 is packaged in a 20-pin plastic dual-in-line package (PDIP, JESD-30 code R-PDIP-T20), a through-hole package well-suited for prototyping and legacy board designs that require socketed or hand-soldered components.
Is the SN74ALS569ANE4 lead-free and RoHS compliant?
Yes, the E4 suffix designates that the SN74ALS569ANE4 is lead-free and RoHS compliant per JESD-609 code e4, meeting environmental regulations for use in commercial, industrial, and restricted-substance markets worldwide.
