SN74LS377NS

Flip Flops Overview

The SN74LS377NS is an octal D-type flip-flop with clock enable, manufactured by Texas Instruments. It features TTL inputs and outputs, housed in a 20-pin DIP package. The device operates within a supply voltage range of 4.75 V to 5.25 V. Key electrical parameters include a propagation delay of 27 ns at 5 V with 15 pF load, high-level output current of -400 µA, and low-level output current of 8 mA. Static current is 28 mA. It supports surface mount installation and functions within a temperature range of 0°C to 70°C.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type flip-flops per unit
• Clock enable functionality for controlled data capture
• TTL-compatible input and output logic levels

Flip Flops Applications

• Data storage registers
• Shift register implementations
• Parallel-to-serial conversion circuits

Flip Flops Procurement Notes

Verify the specific suffix 'N' indicates a through-hole DIP package rather than the 'SR' surface-mount variant. Confirm RoHS compliance status as it may vary by production batch. Check lead times due to potential long delivery periods associated with legacy LS series components. Ensure the supplier provides official datasheets matching the SN74LS377N specification.

Flip Flops Selection Notes

Select this component when TTL logic compatibility is required for octal data storage. Consider the 27 ns propagation delay for timing constraints. Compare against SN74LS377NSR if surface-mount technology is preferred. Evaluate power consumption requirements given the 28 mA static current draw typical of the LS series.

Flip Flops Part Context

Part of the Texas Instruments 74LS series, designed for standard TTL applications. The SN74LS377 family offers octal flip-flops with clock enable. This specific part number represents the through-hole DIP version, distinct from the SOIC surface-mount variants like the SN74LS377NSR.
