74LCXH2245

Low Voltage Bidirectional Transceiver with Bushold

and 26: Series Resistors in B Outputs

General Description

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

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 26

output helps reduce output overshoot and undershoot.

The LCXH2245 is fabricated with an advanced CMOS

technology to achieve high speed operation while maintain-

ing CMOS low power dissipation.

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.

Ordering Code:

Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.

Pb-Free package per JEDEC J-STD-020B.
