74VCX162245

Low Voltage 16-Bit Bidirectional Transceiver with 3.6V

Tolerant Inputs and Outputs and 26Ω Series Resistors in

A Port Outputs

General Description

Features

■ 1.65V–3.6V V_CCsupply operation

The VCX162245 contains sixteen non-inverting bidirec-

tional 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.

■ 3.6V tolerant inputs and outputs

■ 26Ω series resistors in A port outputs

■ t_PD(B to A)

3.4 ns max for 3.0V to 3.6V V_CC

4.3 ns max for 2.3V to 2.7V V_CC

8.6 ns max for 1.65V to 1.95V V_CC

The 74VCX162245 is designed for low voltage (1.65V to

3.6V) V_CCapplications with I/O compatibility up to 3.6V.

■ Power-down high impedance inputs and outputs

■ Supports live insertion/withdrawal (Note 1)

■ Static Drive (I_OH/I_OLA outputs)

The 74VCX162245 is also designed with 26Ω series resis-

tance in the A Port outputs. This design reduces line noise

in applications such as memory address drivers, clock driv-

ers, and bus transceivers/transmitters.

±12 mA @ 3.0V V_CC

±8 mA @ 2.3V V_CC

±3 mA @ 1.65V V_CC

The 74VCX162245 is fabricated with an advanced CMOS

technology to achieve high speed operation while maintain-

ing low CMOS power dissipation.

■ Uses patented noise/EMI reduction circuitry

■ Latchup performance exceeds 300 mA

■ 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 V

through a pull-up resistor; the minimum

value of the resistor is determined by the current-sourcing capability of the

driver.
