74LCXH245

Low Voltage Bidirectional Transceiver with Bushold

General Description

Features

The LCXH245 contains eight non-inverting bidirectional

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

ented applications. The device is designed for low voltage

(2.5V and 3.3V) V_CCapplications. The T/R input deter-

■ 5V tolerant control inputs

■ 2.3V–3.6V V_CCspecifications provided

■ 7.0 ns t_PDmax (V_CC= 3.3V), 10 µA I_CCmax

■ Power down high impedance outputs

■ ±24 mA output drive (V_CC= 3.0V)

mines the direction of data flow through the device. The OE

input disables both the A and B ports by placing them in a

high impedance state.

■ Implements patented noise/EMI reduction circuitry

■ Latch-up performance exceeds 500 mA

The LCXH245 is fabricated with an advanced CMOS tech-

nology to achieve high speed operation while maintaining

CMOS low power dissipation. The LCXH16244 data inputs

include active bushold circuitry, eliminating the need for

external pull-up resistors to hold unused or floating data

inputs at a valid logic level.

■ Bushold on inputs eliminates the need for external

pull-up/pull-down resistors

■ ESD performance:

Human body model > 2000V

Machine model > 200V
