74ALVC162245 Low Voltage 16-Bit Bidirectional Transceiver with 3.6V Tolerant Inputs and Outputs and 26 Series Resistors in A Port Outputs
General Description
The ALVC162245 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 74ALVC162245 is designed for low voltage (1.65V to 3.6V) VCC applications with I/O compatibility up to 3.6V. The 74ALVC162245 is also designed with 26 series resistance in the A Port outputs. This design reduces line noise in applications such as memory address drivers, clock drivers, and bus transceivers/transmitters. The 74ALVC162245 is fabricated with an advanced CMOS technology to achieve high speed operation while maintaining low CMOS power dissipation.

Features
I 1.65V 3.6V VCC supply operation I 3.6V tolerant inputs and outputs I 26 series resistors in A Port outputs I tPD 3.9 ns max for 3.0V to 3.6V VCC 4.8 ns max for 2.3V to 2.7V VCC 8.6 ns max for 1.65V to 1.95V VCC I Power-down high impedance inputs and outputs I Supports live insertion/withdrawal (Note 1) I Uses patented noise/EMI reduction circuitry I Latchup conforms to JEDEC JED78 I ESD performance: Human body model 2000V Machine model 200V
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.
