74VCXH2245

Low Voltage Bidirectional Transceiver with Bushold

and 26Ω Series Resistors in B Outputs

General Description

Features

The VCXH2245 contains eight non-inverting bidirectional

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

ented applications. The T/R input determines the direction

of data flow. The OE input disables both the A and B Ports

by placing them in a high impedance state. The VCXH2245

data inputs include active bushold circuitry, eliminating the

need for external pull-up resistors to hold unused or float-

ing data inputs at a valid logic level.

■ 1.65V-3.6V V_CCsupply operation

■ 3.6V tolerant control inputs

■ Bushold on data inputs eliminates the need for external

pull-up/pull-down resistors

■ 26Ω series resistors in B Port outputs

■ t_PD(A to B)

4.4 ns max for 3.0V to 3.6V V_CC

5.6 ns max for 2.3V to 2.7V V_CC

9.8 ns max for 1.65V to 1.95V V_CC

■ Static Drive (I_OH/I_OLB outputs):

±12 mA @ 3.0V V_CC

The 74VCXH2245 is designed for low voltage (1.65V to

3.6V) V_CCapplications. The VCXH2245 is also designed

with 26Ω series resistance in the B Port outputs. This

design reduces line noise in applications such as memory

address drivers, clock drivers, and bus transceivers trans-

mitters

±8 mA @ 2.3V V_CC

The 74VCXH2245 is fabricated with an advanced CMOS

technology to achieve high-speed operation while main-

taining low CMOS power dissipation.

±3 mA @ 1.65V V_CC

■ Uses patented Quiet Series noise/EMI reduction

circuitry

■ Latchup performance exceeds 300 mA

■ ESD performance:

Human body model > 2000V

Machine model > 200V
