74LCX16646  
Low Voltage 16-Bit Transceiver/Register with 5V Tolerant  
Inputs and Outputs  
General Description  
Features  
5V tolerant inputs and outputs  
The LCX16646 contains sixteen non-inverting bidirectional  
registered bus transceivers with 3-STATE outputs, provid-  
ing multiplexed transmission of data directly from the input  
bus or from the internal storage registers. Each byte has  
separate control inputs which can be shorted together for  
full 16-bit operation.The DIR inputs determine the direction  
of data flow through the device. The CPAB and CPBA  
inputs load data into the registers on the LOW-to-HIGH  
transition (see Functional Description).  
2.3V–3.6V VCC specifications provided  
5.2 ns tPD max (VCC = 3.3V), 20 µA ICC max  
Power down high impedance inputs and outputs  
Supports live insertion/withdrawal (Note 1)  
±24 mA Output Drive (VCC = 3.0V)  
Implements patented noise/EMI reduction circuitry  
Latch-up performance exceeds 500 mA  
The LCX16646 is designed for low voltage (2.5V or 3.3V)  
VCC applications with capability of interfacing to a 5V signal  
ESD performance:  
Human Body Model > 2000V  
Machine Model > 200V  
environment.  
The LCX16646 is fabricated with an advanced CMOS tech-  
nology to achieve high speed operation while maintaining  
CMOS low power dissipation.  
Note 1: To ensure the high-impedance state during power up or down, OE  
should be tied to V  
through a pull-up resistor: the minimum value or the  
CC  
resistor is determined by the current-sourcing capability of the driver.
