SN74LS378N

Flip Flops Overview

The SN74LS378N is a hex D-type flip-flop with clock enable, part of the Texas Instruments LS logic family. It features six independent D-type flip-flops in a 16-pin PDIP package. Key electrical parameters include a maximum propagation delay of 27 ns at 5V and a clock frequency of 35 MHz. The device operates within a supply voltage range of 4.75 V to 5.25 V. Output currents are specified as -400 µA (high) and 8 mA (low). It supports non-inverting outputs and functions within an operating temperature range of 0°C to +70°C.

Flip Flops Feature Summary

• Integrates six independent D-type flip-flops with individual clock enable inputs for precise data latching control.
• Provides non-inverting push-pull TTL outputs capable of driving standard loads.
• Utilizes low-power Schottky (LS) technology to balance speed and power consumption.

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Register storage elements in digital systems
• State machine implementation

Flip Flops Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for end-of-life notices, as legacy LS series components may have limited availability or obsolescence risks. Ensure packaging matches design requirements, specifically the 16-pin PDIP format for through-hole assembly.

Flip Flops Selection Notes

Select this component when hex D-type flip-flops with clock enable are required in through-hole designs. Compare against SN74HC378 for CMOS compatibility or SN74LS377 if latch functionality is preferred. Verify voltage levels match system requirements, as LS logic operates strictly at 5V nominal. Consider pinout compatibility with existing PCB footprints before finalizing the selection.

Flip Flops Part Context

The SN74LS378 belongs to the broader SN74LS37x series of D-type flip-flops and latches from Texas Instruments. It shares architectural similarities with other hex devices in the LS family but distinguishes itself by including clock enable functionality for each bit. This places it alongside variants like the SN74LS377, differing primarily in output type and enable configuration.
