Access from the CPU is stopped. If the device is enabled these inputs determine which one of the 16 normally high outputs will go low. Understand, this is a typical example of application, not it’s sole purpose. All inputs are protected from damagenoise Immunity, 74ld154 low power consumption of CMOS with speeds similar to low power Schottky TTL circuitsInputs deter mine which one of the 16 normally high outputs will go low.

The “Recommended Operating Conditions” table will define the conditions for actual device operation. Two active low enables ST and G2 are provided to ease cascading of decoders with little or no external logic.

Two active low enables GT and G2 are provided to ease cascading of decoders dataheet, V0ut – 0. No abstract text available Text: The unique features of the 8X IV bus and instruction set permit 8-bit parallel data toand merged into any set of from 1 to 8 contiguous bits at the destination. A binary code applied to the four inputs A to D provides a low level at the selected one of sixteen outputs excluding the other fifteen outputsdecoding lines through cascading, and simplifies the design of address decoding circuits in memo ry controlOutput Pin DC Vcc or Ground Current Power Dissipation Storage Temperature Parameter Value All inputs are protected from damage due to static dischargedata routing applications.
