HD74ALVC162834A
18-bit Universal Bus Driver with 3-state Outputs
and Inverted Latch Enable
ADE-205-293A (Z)
2nd. Edition
November 1999
Description
The HD74ALVC162834A 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 low. 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 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.
To ensure the high impedance state during power up or power down,
OE
should be tied to V
CC
through a
pullup registor; the minimum value of the registor is determined by the current sinking capability of the
driver.
All outputs, which are designed to sink up to 12 mA, include series dumping resistors to reduce overshoot
and undershoot.
Features
Supports PC133 and meets “PC SDRAM registered DIMM specification, Rev. 1.1”
