SNJ54LS374FK

The SNJ54LS374FK from Texas Instruments is an octal D-type edge-triggered flip-flop designed for high-speed bus-driving applications. This component features eight flip-flops in a single package, providing 3-state bus-driving outputs capable of handling highly capacitive or low-impedance loads.

Key electrical specifications include a maximum clock frequency of 35 MHz, an output high current of -2.6 mA, and an output low current of 24 mA. The device consumes a maximum supply current of 40 mA. It is built using the LS technology family and features bipolar input type and 3-state output type.

Designed for demanding environments, the SNJ54LS374FK operates across a wide temperature range of -55°C to 125°C, making it suitable for military applications. The package type is FK, and it is typically supplied in a standard package quantity of 20 units. Its high-speed performance and bus-driving capabilities make it ideal for buffer registers, I/O ports, and bidirectional bus drivers in organized systems.

These devices are particularly attractive for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers. The eight flip-flops of the 'LS374 are edge-triggered D-type flip-flops. On the positive transition of the clock, the Q outputs are set to the logic states that were set up at the D inputs.
