Product details

What this buffer does on your bus

The two elements each handle four bits, giving you an 8-bit bus buffer in a single 20-SOIC package.

Supply voltage and temperature — the design envelope

At 5V the HC family's noise margin is comfortable for most board-level buses; at 3.3V the output levels still meet LSTTL thresholds.

20-SOIC wide-body footprint

The 20-SOIC package with 7.50 mm body width is the wide-body variant — not the narrower 3.90 mm SOIC-20. If your board layout expects the narrow body, the pin spacing is the same but the pad-to-pad clearance on the outer rows is tighter.

The 74HC family is a mature logic series with decades of production history, and TI continues to manufacture this part. ROHS3 compliant.

Frequently asked questions

Can SN74HC241DW replace SN74HC240?

The SN74HC240 is an inverting buffer with 3-state outputs, while the SN74HC241DW is non-inverting. They are not drop-in replacements for each other. If your design expects non-inverted data, the SN74HC241DW is the correct choice; if inversion is required, the SN74HC240 serves that purpose.
