Logic device/transceiver/encoder

The AC/ACT139 is a high speed dual 1/4 decoder/demultiplexer. The device features two independent decoders, each accepting two inputs and providing four mutually exclusive active-low outputs. Each decoder has an active low enable input that can be used as the data input for the 4 output demultiplexers. Each half of the AC/ACT139 can be used as a signal generator, providing all four minimum terms of two variables.

The FXLA101 is a configurable dual-voltage supply translator for unidirectional and bidirectional voltage translation between two logic levels. The device enables voltage translation between as high as 3.6V and as low as 1.1V. The A port tracks the VCCA level and the B port tracks the VCCB level. Bidirectional voltage translation between multiple voltage levels: 1.2V, 1.5V, 1.8V, 2.5V and 3.3V. The device will remain tri-stated as long as either VCC=0V, allowing either VCC to power up first. If either VCC is removed, an internal power-down control circuit places the device in 3-state. A high level on the /OE input puts both the A and B ports into a tri-state condition, disabling both. The /OE input is provided by VCCA. The FXLA101 supports bidirectional translation and does not require a direction control pin. Both ports of the device feature automatic orientation sensing. Either port can sense an input signal and pass it on to the other port as an output signal.
