HD74ALVCF162835
18-bit Universal Bus Driver with 3-state Outputs
ADE-205-227E (Z)
Preliminary, 6th. Edition
Feb. 1, 1999
Description
The HD74ALVCF162835 is an 18-bit universal bus driver designed for 2.3 V to 3.6 V V
CC
operation.
Data flow from A to Y is controlled by the output enable (
OE
). The device operates in the transparent mode
when the latch enable (LE) 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 the 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.
To ensure the high impedance state during power up or power down,
OE
should be tied to V
CC
through a
pullup register; the minimum value of the register is determined by the current sinking capability of the
driver.
All outputs, which are designed to sink up to 12 mA, include series resistors to reduce overshoot and
undershoot.
Features
Supports PC133 and meets “PC SDRAM registered DIMM specification, Rev. 0.9”
