FUNCTIONAL BLOCK DIAGRAM
DESCRIPTION:
This 18-bit universal bus driver is built using advanced dual metal CMOS
technology. 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 high. The A data is latched if the clock (CLK) input is held at
a high or low logic level. If 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.
The ALVCF162835A has series resistors in the device output structure
which will reduce switching noise in 128MB and 256MB SDRAM modules.
Designed with a drive capability of ±18mA, the ALVCF162835A is a mid-
way drive between the ALVC162835 (±12mA) and ALVC16835 (±24mA).
The ALVCF162835A is a faster version of the ALVCF162835 or
ALVC162835. It is suitable for PC133 applications and particularly SDRAM
Modules clocked at 133 MHz.
