100328
Low Power Octal ECL/TTL Bi-Directional Translator with
Latch
General Description
The 100328 is an octal latched bi-directional translator de-
signed 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
100328 transparent.
The cut-off state is designed to be more negative than a nor-
mal 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 impedance re-
duces termination power and prevents loss of low state
noise margin when several loads share the bus.
The 100328 is designed with FAST
TTL output buffers, fea-
turing optimal DC drive and capable of quickly charging and
discharging highly capacitive loads. All inputs have 50 k
pull-down resistors.
