SN74HCT574NS

Flip Flops Overview

The SN74HCT574NS is an octal edge-triggered D-type flip-flop manufactured by Texas Instruments. It features three-state outputs and operates within a supply voltage range of 4.5 V to 5.5 V. The device utilizes a 20-pin DIP package for through-hole mounting. Key electrical parameters include a propagation delay of 47 ns at 5.5 V with 150 pF load, and output currents of ±6 mA. It supports a maximum clock frequency of 40 MHz and functions across a temperature range of -40°C to +85°C.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type flip-flops in a single integrated circuit
• Three-state outputs designed for direct bus driving applications
• TTL-compatible input logic levels ensuring interoperability with standard logic families

Flip Flops Applications

• Buffer registers for data storage and transfer
• I/O port implementations in interface circuits
• Bidirectional bus drivers for system communication
• Working registers in digital processing systems

Flip Flops Procurement Notes

Verify the specific suffix 'N' indicates a plastic dual-in-line package (PDIP) variant rather than surface-mount options like 'NSR'. Confirm RoHS compliance status as manufacturing processes may vary. Ensure the supplier provides original manufacturer documentation to validate authenticity against counterfeit components. Check lead times for standard industrial grade availability.

Flip Flops Selection Notes

Select this component when TTL-compatible inputs are required alongside high-speed octal buffering capabilities. The SN74HCT574NS offers a balance of speed and power consumption suitable for 5V logic systems. Consider the PDIP-20 package constraints regarding PCB space compared to SOIC or TSSOP alternatives if board density is a critical factor.

Flip Flops Part Context

This part belongs to the SN74HCT574 family of octal edge-triggered D-type flip-flops. It is distinct from the HC series due to its TTL-compatible input thresholds. The NS designation specifically identifies the 20-pin narrow dual-in-line package format, differentiating it from surface-mount variants such as the NSR or PW versions within the same logical function family.
