74LCX245
Low Voltage Bidirectional Transceiver with 5V Tolerant
Inputs and Outputs
Features
■ 5V tolerant inputs and outputs
■ 2.3V to 3.6V VCC specifications provided
■ 7.0ns tPD max. (VCC = 3.3V), 10A ICC max.
■ Power down high impedance inputs and outputs
■ Supports live insertion/withdrawal(1)
■ ±24mA output drive (VCC = 3.0V)
■
■ Latch-up performance exceeds 500mA
■ ESD performance:
– Human body model
> 2000V
– Machine model
> 200V
■ Leadless DQFN package
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 LCX245 contains eight non-inverting bidirectional
buffers with 3-STATE outputs and is intended for bus
oriented applications. The device is designed for low
voltage (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 LCX245 is fabricated with an advanced CMOS tech-
nology to achieve high speed operation while maintain-
ing CMOS low power dissipation.
