Differential ECL to CMOS/TTL or
LVECL to LVCMOS/LVTTL Translator
TEST AND MEASUREMENT PRODUCTS
Description
The SK10/100ELT25W is a differential ECL to CMOS/
TTL or LVECL to LVCMOS/LVTTL Translator. Because
ECL levels are used, a +5.5V / +3.0V, –5.5V / –3.0V,
and ground supplies are required. The SK10/
100ELT25W is functionally compatible with MC10/
100ELT25.
The small outline 8 pin SOIC package and the single gate
of the SK10/100ELT25W make this device ideal for those
applications where space, performance, and low power
are extremely important.
The V
BB
output allows the ELT25W to also be used in
either single-ended or AC coupled mode. The V
BB
output
should be used only as a bias for the ELT25W as its current
sink/source capability is limited. When used, V
BB
should
be bypassed to ground via a 0.01 µF capacitor.
Under open input conditions, the pull down resistor
on D, and pulldown and pullup resistors on D* will
force the Q output to a TTL low.

At first, I was not used to using fifo, and my mindset was still the mode of 51 that interrupts once for each byte. Later, after I understood the purpose of fifo, I felt that the design of fifo was ve...
