Product details

The 54LS26DM is a TTL NAND gate. It belongs to the 54LS family.

However, it is RoHS non-compliant, which restricts its use in designs that must meet RoHS directives — a common requirement for new equipment sold into the EU or other regulated markets. For RoHS-compliant builds, a lead-free equivalent from the 74LS or 74HCT families would be the typical substitution path.

Sourcing posture

Because it is a legacy TTL gate with active status, supply is generally stable but not stocked in high volume at broadline distributors — expect to order against a firm requirement rather than pull from shelf stock.

Frequently asked questions

What is the replacement for 54LS26DM?

There is no official replacement listed for the 54LS26DM. For RoHS-compliant designs, a lead-free equivalent from the 74LS or 74HCT families is the typical substitution path, but pin compatibility and timing should be verified against the specific application.

What is the difference between 54LS26 and 74LS26?

The 54LS26DM is specified for the extended military temperature range, while the 74LS26 is typically rated for the commercial 0°C to 70°C range. The 54LS prefix also implies tighter process controls and higher reliability screening. For most industrial or commercial applications, the 74LS26 is a cost-effective alternative if the temperature range fits.
