Texas Instruments SN74AC8541/SN74AC8541-Q1 Octal Buffers/Drivers
Texas Instruments SN74AC8541/SN74AC8541-Q1 Octal Buffers/Drivers include Schmitt-trigger inputs and 3-state outputs. The outputs can be simultaneously driven into the high-impedance state using either output enable pins. These buffers/drivers support up to 75mA output drive at 5V in short bursts and drive 50Ω transmission lines. The SN74AC8541-Q1 buffers are AEC-Q100 qualified for automotive applications with device temperature grade 1. These octal buffers/drivers are used to hold a signal during controller reset, debounce a switch, enable or disable a digital signal, and eliminate slow or noisy input signals. The SN74AC8541/SN74AC8541-Q1 buffers/drivers are available in a 4.5mm x 2.5mm size wettable flank QFN package.
