100393
Low Power 9-Bit ECL-to-TTL Translator with Latches
General Description
The 100393 is a 9-bit translator for converting F100K logic
levels to TTL logic levels. A LOW on the latch enable (LE)
latches the data at the input state. A HIGH on the LE
makes the latches transparent. A HIGH on either the ECL
or TTL output enable (OE ECL or OE TTL), holds the out-
puts in a high impedance state.
The 100393 is designed with TTL, 64 mA outputs for Bus
Driving capability. All ECL inputs have 50 kΩ pull-down
resistors. When the inputs are either unconnected or at the
same potential, the outputs will go LOW.
