SN74LS378DR

Flip Flops Overview

The SN74LS378DR is a hex D-type flip-flop with clock enable, manufactured by Texas Instruments in the LS logic series. It features six non-inverting outputs and operates within a supply voltage range of 4.75V to 5.25V. The device exhibits a maximum propagation delay of 27ns at 5V with 15pF load, supporting a clock frequency up to 40MHz. It provides a low-level output current of 8mA and a high-level output current of -400µA. Packaged in a 16-SOIC surface-mount format, it functions reliably across an operating temperature range of 0°C to +70°C.

Flip Flops Feature Summary

• Integrates six independent D-type flip-flops with positive-edge triggering and dedicated clock enable inputs for precise data synchronization control.

Flip Flops Applications

Flip Flops Procurement Notes

Verify the specific suffix 'DR' corresponds to the tape-and-reel packaging configuration required for automated assembly processes. Confirm that the LS logic family specifications align with the target system's power consumption and speed requirements. Ensure the 16-SOIC footprint matches the printed circuit board design constraints before finalizing procurement orders.

Flip Flops Selection Notes

Select this component when a compact solution for storing six bits of data with individual clock gating is necessary. The LS technology offers a balance of moderate speed and standard TTL compatibility suitable for general digital logic designs. Consider the thermal characteristics and current drive capabilities relative to the connected load requirements.

Flip Flops FAQ

What is the trigger type for the internal flip-flops?

The SN74LS378DR utilizes positive-edge triggered D-type flip-flops for data capture.

Does the device include inversion on the outputs?

No, the outputs are non-inverting, meaning they reflect the same logic state as the D input upon clocking.
