Low Voltage 16-Bit Bidirectional Transceiver with

5V Tolerant Inputs/Outputs and Pull-Down Resistors

General Description

Features

■ 5V tolerant inputs and outputs

The LCXP16245 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

■ I/O Pull-down resistors terminate inactive busses ensur-

ing a stable bus state

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.

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

■ Power down high impedance inputs and outputs

■ Supports live insertion/withdrawal (Note 1)

■ ±24 mA output drive (V_CC= 3.0V)

■ Implements patented noise/EMI reduction circuitry

■ Pinout compatible with 74 series 16245

■ Latch-up performance exceeds 500 mA

■ ESD performance:

In addition, A and B port datapath pins have built-in resis-

tors to GND allowing the pins to float without any increase

in I_CCcurrent. This feature is intended to address modular

and space constrained applications where additional space

consumed by external resistors is not available.

Human body model > 2000V

The LCXP16245 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.
