100329
Low Power Octal ECL/TTL Bidirectional Translator
with Register
General Description
The 100329 is an octal registered bidirectional translator
designed to convert TTL logic levels to 100K ECL logic lev-
els and vice versa. The direction of the translation is deter-
mined 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. The outputs change
synchronously with the rising edge of the clock input (CP)
even though only one output is enabled at the time.
The cut-off state is designed to be more negative than a
normal ECL LOW level. This allows the output emitter-fol-
lowers to turn off when the termination supply is 2.0V, pre-
senting a high impedance to the data bus. This high
impedance reduces the termination power and prevents
loss of low state noise margin when several loads share
the bus.
The 100329 is designed with FASTTTL output buffers,
featuring optimal DC drive and capable of quickly charging
and discharging highly capacitive loads. All inputs have
50 kpull-down resistors.

Note 8: The specified limits represent the worst casevalue for the parameter. Since these values normally occur at the temperature extremes, additional
noise immunity and guardbanding can be achieved by decreasing the allowable system operating ranges. Conditions for testing shown in the tables are cho-
sen to guarantee operation under worst caseconditions.

Test Circuitry (TTL-to-ECL)
Note 11: RT = 50termination resistive load. When an input or output is being monitored by a scope, RTis supplied by the scopes 50input resistance.
When an input or output is not being monitored, an external 50resistance must be applied to serve as RT.
Note 12: TTL and ECL force signals are brought to the DUT via 50coax lines.
Note 13: VTTL is decoupled to ground with 0.1 µF, VEE is decoupled to ground with 0.01 µF and VCC is connected to ground.
