SN54LS73AJ Description

Short technical summary and product information.

The SN54LS73AJ is a dual J-K flip-flop integrated circuit manufactured by Motorola Semiconductor. It belongs to the LS technology family and features TTL input compatibility with a Push-Pull output type. This device offers two independent J-K flip-flops, each with individual J-K, clock, and direct clear inputs. It is designed for negative edge triggering and includes high-speed operation with a typical propagation delay between 10-50ns.

 

The SN54LS73AJ operates over a wide temperature range of -55°C to 125°C, making it suitable for military applications. Key electrical characteristics include a maximum supply current of 6000 µA, an IOL of -0.4 mA, and an IOH of 8 mA. The device is available in various package options including CDIP, CFP, and plastic/ceramic DIPs.

 

This flip-flop is ideal for digital logic applications requiring state storage and control. Its clear function overrides other inputs, forcing the Q output low and the Q\ output high when the clear input is low. The high-speed performance and military temperature rating ensure reliability in demanding environments.
