SN74LS378DR

SN74LS378DR Description

The SN74LS378DR is a high-performance D-type flip-flop integrated circuit (IC) designed by Texas Instruments. This single-element, 6-bit flip-flop operates with a clock frequency of up to 40 MHz, ensuring rapid data processing and synchronization. It features a positive edge trigger, which means data is latched on the rising edge of the clock signal, providing precise timing control. The IC is designed for standard logic functions and is suitable for a wide range of digital applications.

The SN74LS378DR operates within a supply voltage range of 4.75V to 5.25V, making it compatible with standard TTL logic levels. It offers a maximum propagation delay of 27ns at 5V and 15pF, ensuring fast signal transmission and minimal latency. The device consumes a quiescent current of 22 mA, which is relatively low, making it energy-efficient for various applications. Additionally, it provides a maximum current output of 400µA for high levels and 8mA for low levels, ensuring robust signal handling capabilities.

The SN74LS378DR is packaged in a 16-pin SOIC (Small Outline Integrated Circuit) package, which is ideal for surface mount applications. It is REACH unaffected and RoHS3 compliant, ensuring environmental safety and regulatory compliance. The device has a moisture sensitivity level (MSL) of 1, which means it is not sensitive to moisture and can be stored and handled without special precautions.
