SN74LS76AN3

Flip Flops Overview

The SN74LS76AN3 is a dual J-K flip-flop from the Texas Instruments LS logic series, housed in a 14-pin PDIP package. It features independent Set and Reset inputs for each flip-flop, with clocking controlled by negative-edge-triggered inputs. The device operates within a supply voltage range of 4.5 V to 5.5 V, supporting standard TTL input levels and providing active-low outputs. Designed for through-hole mounting, it ensures reliable data storage and sequential logic control in digital circuits.

Flip Flops Feature Summary

• Dual independent J-K flip-flops with dedicated Set and Reset controls
• Negative-edge-triggered clock operation for precise timing synchronization
• Active-low Q and non-inverted Q outputs for flexible interfacing
• Standard TTL-compatible input and output characteristics

Flip Flops Applications

• Sequential logic circuit design
• Binary counter construction
• Shift register implementation
• Frequency division circuits

Flip Flops Procurement Notes

Verify the exact manufacturer part number against official Texas Instruments documentation, as 'SN74LS76AN3' may represent a specific packaging or ordering variant distinct from the standard SN74LS76AN. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer's official channels before procurement.

Flip Flops Selection Notes

Select this component when dual J-K flip-flops with asynchronous Set/Reset functionality are required in low-speed TTL applications. Ensure the design accommodates the 14-pin DIP footprint and through-hole assembly process. Verify that the operating temperature range and power supply requirements align with the system specifications.

Flip Flops Part Context

This component belongs to the SN74LSxx series of bipolar TTL logic devices, known for their robust performance in standard digital systems. The SN74LS76 specifically provides two complete J-K flip-flops, offering greater flexibility than D-type alternatives for complex state machine designs requiring toggle or hold modes.

Flip Flops Replacement Considerations

Direct pin-to-pin replacements include the SN74LS76AN (standard commercial grade) and compatible equivalents from other manufacturers such as Fairchild's MC74LS76P or National Semiconductor's SN74LS76N, provided voltage and speed tolerances match.
