Low Voltage 18-Bit Universal Bus Transceivers With 3.6V Tolerant Inputs And Outputs

The ALVC16601 is an 18-bit universal Bus Transceiver which combines D-type Latches and D-type Flip-Flops to allow data flow in transparent, latched, and clocked modes.
Data flow in each direction is controlled by output-enable (OEAB# and OEBA#), latch-enable (LEAB and LEBA), and Clock (CLKAB and CLKBA) inputs. The Clock CAN be controlled by the clock-enable (CLKENAB# and CLKENBA#) inputs. For A-to-B data flow, the device operates in the transparent mode when LEAB is HIGH. When LEAB is LOW, the A data is latched if CLKAB is held at a HIGH-to-LOW Logic level. If LEAB is LOW, the A bus data is stored in the latch Flip-Flop on the LOW-to-HIGH transition of CLKAB. When OEAB# is LOW, the outputs are active. When OEAB# is HIGH, the outputs are in the high-impedance state.
Data flow for B to A is similar to that of A to B but uses OEBA#, LEBA, CLKBA and CLKENBA#.
The ALVC16601 is designed for low voltage (1.65V to 3.6V) VCC applications with I/O capability up to 3.6V.
The ALVC16601 is fabricated with an advanced CMOS technology to achieve high speed operation while maintaining low CMOS power dissipation.
