Flip Flops datasheet and documents for SN74HCT574DW

SN74HCT574DW

Flip Flops Overview

The SN74HCT574DW is an octal edge-triggered D-type flip-flop manufactured by Texas Instruments. It features three-state outputs designed for bus-oriented applications. The device operates within a supply voltage range of 4.5 V to 5.5 V. It accepts TTL-compatible input voltages and provides non-inverting logic. The component is housed in a 20-pin SOIC package suitable for surface-mount installation. Typical propagation delay is specified at 22 ns, with maximum static current consumption of 80 µA.

Flip Flops Feature Summary

Octal edge-triggered D-type flip-flop architecture with three-state outputs
TTL-compatible input voltage levels for direct interface compatibility
High-current non-inverting outputs capable of driving bus lines or multiple loads

Flip Flops Applications

Buffer registers
I/O ports
Bidirectional bus drivers
Working registers

Flip Flops Procurement Notes

Verify the specific suffix indicates the SOIC-20 package configuration. Confirm RoHS compliance status matches project requirements. Ensure the operating temperature range aligns with environmental specifications. Cross-reference the manufacturer part number against official datasheets to confirm functional equivalence before integration.

Flip Flops Selection Notes

Select this component when eight parallel data storage elements are required with bus-driven output capabilities. The HCT series ensures compatibility with standard TTL logic families. Consider the 20-pin SOIC footprint for PCB layout constraints. Evaluate the 22 ns typical propagation delay against system timing requirements.

Flip Flops Part Context

This device belongs to the SN74HCT574 family of octal flip-flops. It shares architectural similarities with other variants like the SN74HC574 but differs in input threshold characteristics. The DW suffix specifically denotes the plastic small-outline package variant. It serves as a core memory element in digital control systems requiring parallel data latching.
