SN74LS604DW

Flip Flops Overview

The SN74LS604DW is an octal bus transceiver manufactured by Texas Instruments in the LS logic series. It features eight independent bidirectional data channels with three-state outputs, housed in a 20-pin SOIC package. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports commercial temperature grades from 0°C to +75°C. Key electrical characteristics include a low-level output current of 24 mA and a high-level output current of -15 mA. Propagation delay is specified at 25 ns, ensuring efficient data transfer for standard TTL-compatible applications.

Flip Flops Feature Summary

• Octal bus transceiver architecture providing eight independent bidirectional data paths
• Three-state outputs enabling direct system bus connections without additional interface hardware
• TTL-compatible input and output levels for seamless integration with standard logic families

Flip Flops Applications

• Bidirectional data bus transmission between microprocessors and memory modules
• I/O port expansion in digital control systems
• Data routing in communication interfaces requiring direction control

Flip Flops Procurement Notes

Verify the specific suffix 'DW' corresponds to the SOIC-20 surface-mount package configuration. Confirm that the component meets RoHS compliance requirements as indicated in official documentation. Ensure the ordering part number matches the exact logic family (LS) and pinout specifications required for the target circuit design before finalizing procurement.

Flip Flops Selection Notes

Select this component when designing systems requiring robust octal bidirectional data transfer with TTL compatibility. The LS logic family offers a balance of speed and power consumption suitable for general-purpose digital applications. Consider the 25 ns propagation delay and 24 mA drive capability when evaluating signal integrity and load requirements for the specific bus topology.

Flip Flops Part Context

This part belongs to the SN74LS6xx series of octal bus transceivers produced by Texas Instruments. It serves as a fundamental building block for digital logic circuits, facilitating data movement between different sections of a system. The DW variant specifically denotes the plastic small-outline integrated circuit package, widely used in surface-mount technology assemblies.

Flip Flops Replacement Considerations

Compatible substitutes include other octal bus transceivers from the same logic family or equivalent devices offering identical pinouts and electrical characteristics. Verify that any replacement maintains the 4.75V–5.25V operating voltage range and TTL compatibility to ensure functional interchangeability without redesigning the surrounding circuitry.
