Texas Instruments High-Performance Analog Integrated Circuits (ICs) - Logic - Flip Flops SN74F378DR

The SN74F378DR is a positive-edge-triggered D-type flip-flop featuring six individual flip-flops with single-rail outputs. It includes a buffered common enable input (CLKEN) that allows for clock enabling, differentiating it from similar models like the SN74F174, which has a common clear. The device transfers data from the D inputs to the Q outputs on the positive edge of the clock pulse when CLKEN is low, ensuring that clock triggering is voltage level-dependent rather than pulse-dependent. This flip-flop operates within a supply voltage range of 4.5V to 5.5V and is characterized for temperatures from 0°C to 70°C. It supports a maximum clock frequency of 110 MHz and has specific timing requirements for setup and hold times, making it suitable for high-speed applications. The SN74F378DR is available in a 16-pin SOIC package and is classified as obsolete, indicating that it may no longer be in production. Engineers should consider this when evaluating its use in new designs.
