74LCXR162245

Low Voltage 16-Bit Bidirectional Transceiver with 5V

Tolerant Inputs/Outputs and 26Ω Series Resistors in the

Outputs

General Description

Features

■ 5V tolerant inputs and outputs

The LCXR162245 contains sixteen non-inverting bidirec-

tional buffers with 3-STATE outputs and is intended for bus

oriented applications. The device is designed for low volt-

age (2.5V or 3.3V) V_CCapplications with capability of inter-

■ 2.3V–3.6V V_CCspecifications provided

■ A and B side outputs have equivalent 26Ω series

resistors

facing to a 5V signal environment. The device is byte

controlled. Each byte has separate control inputs which

could 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.

■ 5.3 ns t_PDmax (V_CC= 3.3V), 20 µA I_CCmax

■ Power down high impedance inputs and outputs

■ Supports live insertion/withdrawal (Note 1)

■ Flow through pinout

■ Implements patented noise/EMI reduction circuitry

■ Latch-up performance exceeds 500 mA

■ ESD performance:

In addition, all A and B outputs include equivalent 26Ω

(nominal) series resistors to reduce overshoot and under-

shoot and are designed to sink/source up to 12 mA at

V_CC= 3.0V.

Human body model > 2000V

The LCXR162245 is fabricated with an advanced CMOS

technology to achieve high speed operation while maintain-

ing CMOS low power dissipation.

Machine model > 200V

Note 1: To ensure the high-impedance state during power up or down OE

should be tied to V

through a pull-up resistor: the minimum value or the

resistor is determined by the current-sourcing capability of the driver.
