74LCX16245  
Low voltage CMOS 16-bit bus transceiver (3-state)  
with 5V tolerant inputs and outputs  
Features  
■ 5V tolerant inputs and outputs  
■ High speed:  
– t = 4.5ns (Max) at V = 3V

Description

PHL  
PLH  
The 74LCX16245 is a low voltage CMOS 16 bit  
bus transceiver (3-state) fabricated with sub-  
micron silicon gate and double-layer metal wiring  
■ Operating voltage range:  
– V (Opr) = 2.0V to 3.6V  
CC  
2
C MOS technology. It is ideal for low power and  
■ Pin and function compatible with  
high speed 3.3V applications; it can be interfaced  
to 5V signal environment for both inputs and  
outputs.  
74 series 16245  
■ Latch-up performance exceeds  
500mA (JESD 17)  
This IC is intended for two-way asynchronous  
communication between data buses; the direction  
of data transmission is determined by DIR input.  
■ ESD performance:  
– HBM > 2000V  
(MIL STD 883 method 3015); MM > 200V  
The two enable inputs nG can be used to disable  
the device so that the buses are effectively  
isolated.  
It has same speed performance at 3.3V than 5V  
AC/ACT family, combined with a lower power  
consumption.  
All inputs and outputs are equipped with  
protection circuits against static discharge, giving  
them 2KV ESD immunity and transient excess  
voltage.  
All floating bus terminals during High Z State must  
be held HIGH or LOW.
