Product details

Buffer, Non-Inverting with 3-State — 2V to 6V supply

It operates across a wide supply range of 2V to 6V, making it suitable for mixed-voltage or battery-backed systems. Each of the two elements handles 4 bits, with a symmetric output drive of 7.8mA for both high and low states. The 3-state outputs allow direct connection to shared data buses when the output-enable control is deasserted.

Through-hole 20-DIP package

Housed in a 20-pin DIP with 0.300-inch (7.62mm) body width, the CD74HC241E is a through-hole device (20-PDIP supplier package). This footprint suits prototyping boards, legacy socketed designs, and applications where hand-assembly or rework is preferred over surface-mount.

Lifecycle and compliance

Listed as Active by Texas Instruments with RoHS3 compliance. The 74HC family is widely second-sourced; for a pin-compatible alternate from the same logic family, the 74HCT241 (TTL-compatible input thresholds) is a drop-in swap if the input levels match your system.

Frequently asked questions

What is the difference between CD74HC241E and CD74HC244?

Both are 74HC octal buffers with 3-state outputs in a 20-pin DIP. The CD74HC241 has non-inverting outputs with split direction control (two groups of four with independent output enables), while the CD74HC244 is also non-inverting but uses a simpler dual 4-bit arrangement with two active-low output-enable pins. The 241 offers more flexible bus control for bidirectional or partitioned data paths.
