Low Voltage 32-Bit Bidirectional Transceiver

with 5V Tolerant Inputs and Outputs with Bushold

General Description

Features

■ 5V tolerant inputs and outputs

The LCXH32245 contains thirty-two 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 to 3.6V V_CCspecifications provided

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

■ Power-off high impedance inputs and outputs

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

controlled. Each byte has separate control inputs which

could be shorted together for full 32-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.

■ Bushold on inputs eliminates the need for external

pull-up/down resistors

■ Supports live insertion/withdrawal (Note 1)

■ ±24 mA output drive (V_CC= 3.0V)

■ Uses patented noise/EMI reduction circuitry

■ Latch-up performance exceeds 500 mA

■ ESD performance:

The LCXH32245 data inputs include bushold, eliminating

the need for external pull-up/down resistors to hold unused

inputs.

The LCXH32245 is fabricated with an advanced CMOS

technology to achieve high speed operation while maintain-

ing CMOS low power dissipation.

Human body model > 2000V

Machine model > 200V

■ Packaged in plastic Fine-Pitch Ball Grid Array (FBGA)

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

should be tied to VCC through a pull-up resistor: the minimum value or the

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