74LCXZ2245
Low Voltage Bidirectional Transceiver
with 5V Tolerant Inputs and Outputs
and 26Series Resistors in B Outputs
General Description
The LCXZ2245 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
(2.7V and 3.3V) VCC applications with capability of interfac-
ing 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 26series resistor in the B Port out-
put helps reduce output overshoot and undershoot.
The LCXZ2245 is fabricated with an advanced CMOS
technology to achieve high speed operation while maintain-
ing CMOS low power dissipation.
When VCC is between 0 and 1.5V, the LCXZ2245 is on the
high impedance state during power up or power down. This
places the outputs in the high impedance (Z) state prevent-
ing intermittent low impedance loading or glitching in bus
oriented applications.
Features
s 5V tolerant inputs and outputs
s 2.7V–3.6V VCC specifications provided
s 7.0 ns tPD max (VCC = 3.3V), 10 µA ICC max
s Power down high impedance inputs and outputs
s Supports live insertion/withdrawal (Note 1)
s ±12 mA output drive on the B Port (VCC = 3.0V)
s Implements patented noise/EMI reduction circuitry
s Latch-up performance exceeds 500 mA
s Equivalent 26series resistor on all B Port outputs
s 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.
