AI Summary

SN74HCT74N by Texas Instruments: Flip Flop 2 Element D-Type 1 Bit Positive Edge 14-DIP (0.300", 7.62mm).

The SN74HCT74NE4 is the direct lead-free (RoHS compliant) version of the SN74HCT74N from the same manufacturer. It provides a seamless drop-in transition with zero physical or electrical deviations.

  • Direct pin-compatible drop-in replacement
  • Identical electrical characteristics and propagation delays
  • Lead-free (RoHS compliant) E4 suffix variant from the same manufacturer

The CD74HCT74E belongs to the legacy Harris/RCA product line now manufactured by Texas Instruments. It functions as a direct drop-in replacement with a slightly extended temperature range and a marginally faster maximum clock speed.

  • Pin-compatible drop-in replacement in the same 14-PDIP footprint
  • Slightly higher clock frequency capability (50 MHz vs 46 MHz)
  • Wider industrial operating temperature range (-55°C to 125°C vs -40°C to 85°C)
  • Slightly larger input capacitance (10 pF vs 3 pF)
  • Slightly higher maximum propagation delay (35ns vs 25ns)

You searched one part. Parter watches your whole BOM.

  1. All your BOM, at once

    Parter maps every line to live stock, lead time, lifecycle and compliance data across the entire market — not part by part.

  2. Hear about problems before they hit production

    Allocation, EOL and last-time-buy notices surface the moment they appear, not when your buyer's PO bounces.

  3. Qualified replacements in minutes, not days

    Every at-risk line gets form-fit-function matches like the ones above — deltas flagged, evidence attached. Review, push to your BOM, and Parter starts watching the new part too.
