74ACQ241PC Equivalent & Substitute Parts

Part Overview

The 74ACQ241PC is a non-inverting buffer IC manufactured by onsemi, featuring 2 elements with 4 bits per element and 3-state output capability. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. The 74ACQ241PC operates across a 2V to 6V supply voltage range with 24mA output current capability in both high and low states, housed in a 20-DIP package suitable for through-hole mounting applications.
