SN74LS377DW

Flip Flops Overview

The SN74LS377DW is an octal D-type flip-flop register manufactured by onsemi, utilizing Low Power Schottky (LS) technology. It integrates eight positive edge-triggered D-type flip-flops with a buffered common clock and a buffered common clock enable input. The device features non-inverting outputs and is housed in a 20-SOIC surface-mount package. It operates within a supply voltage range of 4.75 V to 5.25 V and supports a maximum clock frequency of 40 MHz. The propagation delay is specified at 27 ns under standard test conditions.

Flip Flops Feature Summary

• Integrates eight positive edge-triggered D-type flip-flops for parallel data storage
• Includes buffered common clock and clock enable inputs for synchronized control
• Utilizes Low Power Schottky technology for high-speed operation with reduced power consumption

Flip Flops Applications

• High-speed parallel data registers
• Digital signal processing systems
• Memory buffer applications

Flip Flops Procurement Notes

Verify the manufacturer designation carefully, as the SN74LS377DW part number is historically associated with Texas Instruments. Confirm that the specific unit provided is explicitly sourced from onsemi or an authorized distributor listing onsemi as the manufacturer. Ensure the datasheet matches the onsemi specification sheet to validate technical parameters and pinout compatibility before integration into designs.

Flip Flops Selection Notes

Select this component when an octal register with a common enable function is required in Low Power Schottky logic families. It serves as a direct functional replacement for other 74LS377 variants across different manufacturers, provided the SOIC-20 package and LS electrical characteristics align with the system requirements. Verify temperature range and output drive capabilities against the specific application load.

Flip Flops Part Context

This component belongs to the 74LS series of digital logic integrated circuits, specifically designed for octal register applications. The 74LS377 architecture provides eight independent D-type flip-flops sharing a single clock and enable line, facilitating efficient data latching in complex digital systems. It represents a standard solution for parallel-to-serial conversion interfaces and temporary data storage in microprocessor-based designs.
