SN74LS107AN

Flip Flops Overview

The SN74LS107AN is a dual J-K flip-flop integrated circuit from the Texas Instruments LS logic series. It features two independent negative-edge triggered circuits with complementary outputs and asynchronous clear inputs. The device operates within a supply voltage range of 4.75 V to 5.25 V, supporting a maximum clock frequency of 45 MHz. Key electrical parameters include a propagation delay of 20 ns, a low-level output current of 8 mA, and a high-level output current of -400 uA. It is housed in a 14-pin PDIP package and functions reliably across an operating temperature range of 0°C to +70°C.

Flip Flops Procurement Notes

Verify the specific manufacturer source, as the SN74LS107AN part number has been produced by multiple vendors including Texas Instruments and Motorola/NXP. Confirm that the received component matches the intended datasheet specifications regarding pinout and electrical limits. Ensure the package type corresponds to the required PCB footprint and mounting style before finalizing procurement orders.

Flip Flops Selection Notes

Select this component when designing TTL-based sequential logic requiring dual J-K functionality with asynchronous clearing. It is suitable for through-hole assembly applications where standard LS logic speed and drive capabilities are sufficient. Consider alternative packages such as SOIC or variants like the SN74ALS107 if surface-mount technology or lower power consumption is required for the specific design constraints.

Flip Flops Part Context

This component belongs to the standard 74LS (Low-power Schottky) family of digital logic ICs. It provides a cost-effective solution for basic memory elements in digital systems. The SN74LS107AN serves as a fundamental building block for creating complex state machines and data storage units within legacy or industrial control architectures utilizing standard TTL interfaces.

Flip Flops Replacement Considerations

The SN74LS107ANSR is a tape-and-reel variant of the same functional device in an SOIC-14 package. Cross-vendor equivalents such as the Motorola SN74LS107ANDS offer identical logical operations but may require verification of mechanical dimensions and minor electrical parameter tolerances against the original specification sheet.
