•Operates From1.65V to3.6V
•ESD Protection Exceeds JESD22
•Inputs Accept Voltages to5.5V
–2000-V Human-Body Model(A114-A)
•Max t pd of6.2ns
–200-V Machine Model(A115-A)
•Typical V OLP(Output Ground Bounce)
<0.8V at V CC=3.3V,T A=25°C–1000-V Charged-Device Model(C101)•Typical V OHV(Output V OH Undershoot)
>2V at V CC=3.3V,T A=25°C
This dual2-line to4-line decoder/demultiplexer is designed for1.65-V to3.6-V V CC operation.
The device comprises two individual2-line to4-line decoders in a single package.The active-low enable(G) input can be used as a data line in demultiplexing applications.This decoder/demultiplexer features fully buffered inputs,each of which represents only one normalized load to its driving circuit.
Inputs can be driven from either3.3-V or5-V devices.This feature allows the use of this device as a translator in a mixed3.3-V/5-V system environment.
