DESCRIPTION/ORDERING INFORMATION  
This 18-bit universal bus driver is designed for 2.3-V  
to 3.6-V VCC operation.

output-enable (OE) input. The device operates in the  
transparent mode when the latch-enable (LE) input is  
high. When LE is low, the A data is latched if the  
clock (CLK) input is held at a high or low logic level. If  
LE is low, the A data is stored in the latch/flip-flop on  
the low-to-high transition of CLK. When OE is high,  
the outputs are in the high-impedance state.

NC − No internal connection  
The SN74ALVCF162835 has series damping  
resistors in the device output structure that reduce  
switching noise in 128-MB and 256-MB SDRAM  
modules. Designed with a drive capability of ±18 mA,  
this device is  
a
midway drive between the  
SN74ALVC162835 (±12 mA) and SN74ALVC16835  
(±24 mA).
