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.
