74LCXH2245  
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) VCC applications. The T/R input deter-  
■ 2.3V–3.6V VCC specifications 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 tPD max (VCC = 3.3V), 10 µA ICC max  
■ Power down high impedance outputs  
■ ±12 mA output drive B Port (VCC = 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.
