CD54AC191F3A Product Details

CD54AC191F3A Overview


A CDIPpackage is used for this device. Using 16terminations, it can be configured. 3.3Vis fully flexible due to its voltage supply. There are 16pins on all components. The device is mounted in the direction of [0]. It is included in the ACfamily. The device stores 4bits of information. Based on Pbfree code, this may result in no. A temperature grade of MILITARYis specified for this device. In this case, 3.3/5Vvoltage is generated by the voltage source. This device operates at 125°C°C for extended periods of time with acceptable electrical stability. Temperature ranges are specified, with -55°Cset as a lower limit. It reaches 5.5Vvoltage at its maximum. The device can operate at as low a voltage as 1.5V. During quiescent mode, it consumes 8μA current.
