SN74LS76AN

Flip Flops Overview

The SN74LS76AN is a dual J-K flip-flop integrated circuit manufactured by Texas Instruments. It operates within the standard TTL logic family and features independent preset and clear inputs for direct control of output states. The device utilizes a 14-pin plastic dual in-line package (PDIP) designed for through-hole mounting on printed circuit boards. It supports negative-edge triggering to synchronize data capture with clock signals. The component functions reliably across a specified temperature range and voltage supply, providing robust performance for sequential logic applications requiring reliable state retention and controlled toggling.

Flip Flops Feature Summary

• Dual J-K flip-flops with independent preset and clear inputs
• Negative-edge triggered operation for precise timing synchronization
• Standard TTL logic compatibility for broad system integration

Flip Flops Applications

• Binary counters and frequency dividers
• Shift registers for serial-to-parallel data conversion
• Sequential control circuits in digital systems

Flip Flops Procurement Notes

Verify the specific manufacturer part number against official Texas Instruments documentation to confirm pinout and electrical characteristics. Ensure the procurement source provides valid RoHS compliance information if required by your design specifications. Cross-reference the datasheet revision date to ensure compatibility with current manufacturing standards. Confirm that the packaging type matches your assembly requirements before finalizing orders.

Flip Flops Selection Notes

Select this component when designing circuits requiring dual independent storage elements with asynchronous control capabilities. It is suitable for applications needing negative-edge triggering within standard TTL voltage levels. Consider the PDIP package constraints regarding board space and thermal dissipation. Evaluate the propagation delay and power consumption characteristics against other logic families if higher speed or lower power is critical for the specific application environment.

Flip Flops Part Context

This component belongs to the Texas Instruments SN74LS series, which represents low-power Schottky TTL technology. This family offers a balance between switching speed and power consumption compared to standard TTL variants. The SN74LS76AN specifically addresses needs for dual flip-flop configurations in legacy and industrial digital designs. Its widespread adoption stems from its reliability and standardized interface within the broader 7400-series logic ecosystem.

Flip Flops Replacement Considerations

Compatible substitutes include the SN54LS76J for military-grade temperature ranges and the SN74LS76N from other manufacturers adhering to the same pinout and electrical specifications. Verify functional equivalence regarding preset and clear logic levels before substitution.
