Low Voltage Bidirectional Transceiver with Bushold

and 26Ω Series Resistors in B Outputs

General Description

Features

■ 5V tolerant control inputs

The LCXH2245 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-

■ 2.3V–3.6V V_CCspecifications provided

■ Bushold on inputs eliminates the need for external

pull-up/pull-down resistors

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. The 26Ω series resistor in the B Port

output helps reduce output overshoot and undershoot.

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

■ Power down high impedance outputs

■ ±12 mA output drive B Port (V_CC= 3.0V)

The LCXH2245 is fabricated with an advanced CMOS

technology to achieve high speed operation while maintain-

ing CMOS low power dissipation.

■ Implements patented noise/EMI reduction circuitry

■ Latch-up performance exceeds 500 mA

■ Equivalent 26Ω series resistor on B Port outputs

■ ESD performance:

The LCXH2245 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.
