SNJ54ALS374AJ

The SNJ54ALS374AJ from Texas Instruments is an octal D-type edge-triggered flip-flop featuring 3-state outputs. This component is specifically designed for driving highly capacitive or relatively low-impedance loads, making it ideal for applications such as buffer registers, I/O ports, and bidirectional bus drivers.

On the positive transition of the clock input, the Q outputs are set to the logic levels present at the D inputs. A buffered output-enable (OE) input controls the eight outputs, allowing them to be in a normal logic state or a high-impedance state. This high-impedance state enables the outputs to drive bus lines without requiring interface or pullup components, while OE does not affect internal flip-flop operations.

This device operates over a military temperature range of -55°C to 125°C. It offers a maximum clock frequency of up to 75 MHz with a propagation delay as low as 10 ns (CL=15pF). The flip-flop is available in a J package.

Key specifications include 8 circuits, D-type logic, 3-state outputs, and a wide operating temperature range. The SNJ54ALS374AJ is suitable for demanding applications requiring reliable digital logic functions.
