This 18-bit universal bus driver is designed for 2.3-V to 3.6-V VCC operation.
Data flow from A to Y is controlled by the 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.
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.
