Additional Details

The 54F158ADMQB is typically packaged in a ceramic dual-in-line package (CERDIP) designed for military and aerospace applications, indicated by the 'MQB' suffix. This packaging provides enhanced reliability and temperature performance compared to standard plastic packages. The device selects one of two inputs for each of the four multiplexer channels based on the state of a common select input. A separate enable input allows the outputs to be disabled. Detailed specifications, including propagation delays, power consumption, and operating temperature range, are available in the device datasheet. Proper decoupling capacitors should be used to minimize noise and ensure stable operation.
