74LCXR2245
Low Voltage Bidirectional Transceiver with 5V Tolerant Inputs
and Outputs and 26
Series Resistors on Both A and B Ports
Features
■ 5V tolerant inputs and outputs
■ 2.3V–3.6V VCC specifications provided
■ 8.0ns tPD max. (VCC = 3.3V), 10A ICC max.
■ Power down high impedance inputs and outputs
■ Supports live insertion/withdrawal(1)
■ ±12mA output drive (VCC = 3.0V)
■
■ Latch-up performance exceeds 500mA
■ Equivalent 26
series resistor on all outputs
■ ESD performance:
– Human body model
> 2000V
– Machine model
> 200V
Note:
1. To ensure the high-impedance state during power up
or down, OE should be tied to VCC through a pull-up
resistor: the minimum value or the resistor is
determined by the current-sourcing capability of the
driver.
General Description
The LCXR2245 contains eight non-inverting bidirectional
buffers with 3-STATE outputs and is intended for bus ori-
ented applications. The device is designed for low volt-
age (2.5V and 3.3V) VCC applications with capability of
interfacing to a 5V signal environment. The T/R input
determines 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
series resistor
helps reduce output overshoot and undershoot.
The LCXR2245 is fabricated with an advanced CMOS
technology to achieve high speed operation while main-
taining CMOS low power dissipation.
Ordering Information
Device also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering number.
All packages are lead free per JEDEC: J-STD-020B standard.
