74LCX16245
Low Voltage 16-Bit Bidirectional Transceiver with
5V Tolerant Inputs and Outputs
General Description
The LCX16245 contains sixteen 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 or 3.3V) VCC applications with capability of interfac-
ing to a 5V signal environment. The device is byte con-
trolled. Each byte has separate control inputs which could
be shorted together for full 16-bit operation. The T/R inputs
determine the direction of data flow through the device.
The OE inputs disable both the A and B ports by placing
them in a high impedance state.
The LCX16245 is fabricated with an advanced CMOS tech-
nology to achieve high speed operation while maintaining
CMOS low power dissipation.
Features
s 5V tolerant inputs and outputs
s 2.3V–3.6V VCC specifications provided
s 4.5 ns tPD max (VCC = 3.3V), 20 µA ICC max
s Power down high impedance inputs and outputs
s Supports live insertion/withdrawal (Note 1)
s ±24 mA output drive (VCC = 3.0V)
s Implements patented noise/EMI reduction circuitry
s Latch-up performance exceeds 500 mA
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.
