100395
Low Power 9-Bit ECL-to-TTL Translator with Registers
General Description
The 100395 is a 9-bit translator for converting F100K logic
levels to TTL logic levels. A HIGH on the output enable
(OE) holds the TTL outputs in a high impedance state. Two
separate clock inputs are available for multiplexing and
system level testing.
The 100395 is designed with TTL 64 mA outputs for bus
driving capability. All inputs have 50 k? pull down resistors.
When the inputs are either unconnected or at the same
potential, the outputs will go LOW.
