It operates from a 2V to 3.6V supply and can sink or source 24mA per output, making it suitable for driving bus lines or high-capacitance loads in mixed-voltage systems. Housed in a 20-TSSOP package (4.40mm width, 0.173\" pitch), the 74LCX540MTC is a surface-mount device. The fine-pitch TSSOP footprint demands careful PCB layout for signal integrity, especially when routing the 8-bit bus at higher toggle rates. Supplied in Tube packaging for through-hole assembly or small-batch rework.","metaTitle":"onsemi 74LCX540MTC Buffer Invert, 3-State, 20-TSSOP","metaDescription":"Active onsemi 74LCX540MTC 8-bit inverting buffer with 3-state outputs, 2V-3.6V supply, 24mA drive, -40 to 85°C.
