Product details

What the 74HCT family means for your 5V logic design

The SN74HCT244N: Each of the two 4-bit elements drives 6mA high and 6mA low, enough to fan out to two or three standard TTL loads but not to drive long backplane traces or high-capacitance bus lines without external buffering.

Through-hole 20-DIP — breadboard and socket friendly

Housed in a 20-pin DIP with 0.300-inch (7.62mm) body width, the SN74HCT244N fits standard DIP sockets and perfboard — you can hand-solder it without magnification, and it's a natural fit for a weekend prototype or a one-off repair.

Active lifecycle and compliance — no end-of-life concerns

ROHS3 compliant, with no lead, cadmium, or other restricted substances — fits RoHS-directed BOMs without an exemption.
