74VCX16245 Low Voltage 16-Bit Bidirectional Transceiver with 3.6V Tolerant Inputs and Outputs
October 1996 Revised November 2002
74VCX16245 Low Voltage 16-Bit Bidirectional Transceiver with 3.6V Tolerant Inputs and Outputs
General Description
The VCX16245 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 74VCX16245 is designed for low voltage (1.2V to 3.6V) VCC applications with I/O compatibility up to 3.6V. The 74VCX16245 is fabricated with an advanced CMOS technology to achieve high speed operation while maintaining low CMOS power dissipation.
Features
s 1.2V to 3.6V VCC supply operation s 3.6V tolerant inputs and outputs s tPD 2.5 ns max for 3.0V to 3.6V VCC s Power-off high impedance inputs and outputs s Supports live insertion/withdrawal (Note 1) s Static Drive (IOH/IOL)
±24 mA @ 3.0V VCC
s Uses patented noise/EMI reduction circuitry s Latchup performance exceeds 300 mA s ESD performance: Human body model > 2000V Machine model >200V s Also packaged in plastic Fine-Pitch Ball Grid Array (FBGA)
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" table are not guaranteed at the Absolute Maximum Ratings. The Recommended Operating Conditions tables will define the conditions for actual device operation. Note 5: IO Absolute Maximum Rating must be observed. Note 6: Floating or unused pin (inputs or I/O's) must be held HIGH or LOW.
