The 74LCX16244 is a low voltage CMOS 16 bit  
bus buffer (non-inverted) 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 16244  
Latch-up performance exceeds  
500mA (JESD 17)  
Any nG output control governs four BUS  
BUFFERS. Output Enable input (nG) tied together  
gives full 16-bit operation.  
ESD performance:  
– HBM > 2000V  
(MIL STD 883 method 3015); MM > 200V  
When nG is LOW, the outputs are on. When nG is  
HIGH, the output are in high impedance state.  
This device is designed to be used with 3 state  
memory address drivers, etc.  
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.
