74ALVC16245 Low Voltage 16-Bit Bidirectional Transceiver with 3.6V Tolerant Inputs and Outputs
October 2001 Revised October 2001
74ALVC16245 Low Voltage 16-Bit Bidirectional Transceiver with 3.6V Tolerant Inputs and Outputs
General Description
The ALVC16245 contains sixteen non-inverting bidirectional buffers with 3-STATE outputs and is intended for bus oriented applications. The device is byte controlled. Each byte has separate 3-STATE control inputs which can be shorted together for full 16-bit operation. The T/R inputs determine the direction of data flow through the device. The OE inputs disable both the A and B ports by placing them in a high impedance state. The 74ALVC16245 is designed for low voltage (1.65V to 3.6V) VCC applications with I/O compatibility up to 3.6V. The 74ALVC16245 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 3.0 ns max for 3.0V to 3.6V VCC 3.5 ns max for 2.3V to 2.7V VCC 6.0 ns max for 1.65V to 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 4: 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 5: IO Absolute Maximum Rating must be observed. Note 6: Floating or unused control inputs must be held HIGH or LOW.
