LOW POWER OCTAL ECL/TTL BI-DIRECTIONAL TRANSLATOR WITH
LATCH
General Description
The F100328 is an octal latch bi-directional translator designed to convert TTL logic
levels to 100K ECL logic levels and vice versa. The direction of this translation is
determined by the DIR input. A LOW on the output enable input (OE) holds the ECL outputs
in a cut-off state and the TTL outputs at a high impedance level. A HIGH on the latch
enable input (LE) latches the data at both inputs even though only one output is enabled
at the time. A LOW on LE makes the F100328 transparent. The cut-off state is designed to
be more negative than a normal ECL LOW level. This allows the output emitter-followers to
turn off when the termination supply is -2.0V, presenting a high impedance to the data
bus. This high inpedance reduces termination power and prevents loss of low state noise
margin when several loads share the bus.
The F100328 is designed with FAST TTL output buffers, featuring optimal DC drive and
capable of quickly charging and discharging highly capacitive loads. All inputs have 50K
ohm pull-down resistors.
