DESCRIPTION/ORDERING INFORMATION

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  
low. When LE is high, the A data is latched if the  
clock (CLK) input is held at a high or low logic level. If  
LE is high, 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 ALVCF162834 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 ALVC162834 (±12 mA) and ALVC16834 (±24 mA).  
The SN74ALVCF162834 is a faster version of the SN74ALVC162834. It is suitable for PC133 applications,  
particularly for SDRAM modules clocked at 133 MHz.  
To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup  
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
