74FR543SCX Overview

Under a temperature of 0°C, buffers can operate. Ambient temperatures should not exceed 70°C. When it is set to low-level output, voltage buffer outputs 64mA. It is possible for the electronic part to conduct -15mA of current when operating on high-level output mode. There should be a voltage at least of 4.5V used to run this buffer. As far as maximum supply voltage is concerned, it is rated at 5.5V. 1 circuits are at the heart of it's fundamental operation.
