Datasheet General Purpose CMOS Logic IC Quad 2-Input NAND Schmitt Trigger BU4093B BU4093BF BU4093BFV General Description Key Specifications BU4093B, BU4093BF, BU4093BFV consist of four Operating Supply Voltage Range: +3V to +16V independent 2-input NAND gates with Schmitt-trigger Input Voltage Range: 0V to V DD function on all inputs. An inverter-based buffer is Operating Temperature Range: -40C to +85C incorporated at the gate output to improve I/O transmission characteristics, and it minimizes a variation in the propagation time caused by an increase in the load capacitance.

Reduce 4.5mW per 1C above 25C (Note 3) Mounted on 70mm x 70mm x 1.6mm glass epoxy board. Reduce 7.0mW per 1C above 25C Caution: Operating the IC over the absolute maximum ratings may damage the IC. The damage can either be a short circuit between pins or an open circuit between pins and the internal circuitry. Therefore, it is important to consider circuit protection measures, such as adding a fuse, in case the IC is operated over the absolute maximum ratings.
