74ALVC16601 Low Voltage 18-Bit Universal Bus Transceivers with 3.6V Tolerant Inputs and Outputs
General Description
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-toLOW 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.
Features
s 1.65V-3.6V VCC supply operation s 3.6V tolerant inputs and outputs s tPD (A to B, B to A) 3.4 ns max for 3.0V to 3.6V VCC 4.0 ns max for 2.3V to 2.7V VCC 7.0 ns max for 1.65V 1.95V VCC s Power-down high impedance inputs and outputs s Supports live insertion/withdrawal (Note 1) s Uses patented noise/EMI reduction circuitry s Latchup conforms to JEDEC JED78 s ESD performance: Human body model > 2000V Machine model >200V s Also packaged in plastic Fine-Pitch Ball Grid Array (FBGA) (Preliminary)
Note 1: To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pull-up resistor; the minimum value of the resistor is determined by the current-sourcing capability of the driver.

Note 7: The Absolute Maximum Ratings are those values beyond which the safety of the device cannot be guaranteed. The device should not be operated at these limits. The parametric values defined in the Electrical Characteristics tables are not guaranteed at the Absolute Maximum Ratings. The "Recommended Operating Conditions" table will define the conditions for actual device operation. Note 8: IO Absolute Maximum Rating must be observed.
