For A-to-B data flow, thePower-down high impedance inputs and outputs device operates in the transparent mode when LEAB is Supports live insertion/withdrawal (Note 1) HIGH. When LEAB is LOW, the A data is latched if CLKAB Static Drive (I /I ) OH OL is held at a HIGH or LOW logic level. If LEAB is LOW, the A bus data is stored in the latch/flip-flop on the LOW-to-HIGH ±24 mA @ 3.0V V CC transition of CLKAB. When OEAB is HIGH, the outputs are Uses patented noise/EMI reduction circuitry active. When OEAB is LOW, the outputs are in a high- Latchup performance exceeds 300 mA impedance state. ESD performance: Data flow for B to A is similar to that of A to B but uses Human body model > 2000V OEBA, LEBA, and CLKBA. The output enables are com- plementary (OEAB is active HIGH and OEBA is active Machine model >200V LOW). Note 1: To ensure the high-impedance state during power up or power down, OEBA should be tied to V through a pull-up resistor and OEAB The VCX16501 is designed for low voltage (1.4V to 3.6V) CC should be tied to GND through a pull-down resistor; the minimum value of V applications with I/O capability up to 3.6V. CC the resistors is determined by the current-sourcing capability of the driver. The VCX16501 is fabricated with an advanced CMOS technology to achieve high speed operation while maintain- ing low CMOS power dissipation.
