description
Function Table
This octal TTL-to-ECL translator is designed to
provide efficient translation between a TTL signal
environment and a 100K ECL signal environment.
This device is designed specifically to improve the
performance and density of TTL-to-ECL CPU/
bus-oriented functions such as memoryaddress drivers,clock drivers, and bus-oriented
receivers and transmitters.
The eight flip-flops of the ’5578 are edge-triggered
D-type flip-flops. On the positive transition of the
clock, the Q outputs are set to the logic levels that
were set up at the D inputs.
The output-control input OE does not affect the
internal operations of the flip-flops. Old data can
be retained or new data can be entered while the
outputs are off.

‡ The algebraic convention, in which the least positive (most negative) value is designated minimum, is used in this data sheet for logic levels only.
§ All typical values are at VCC = 5 V, VEE = – 4.5 V, TA = 25°C.
NOTES: 2. Each 100KT series circuit has been designed to meet the dc specifications shown in the test table after thermal equilibrium has been
established. The circuit is in a test socket or mounted on a printed circuit board and transverse air flow greater than 500 linear ft/min
is maintained.
3. Outputs are terminated through a 50-Ω resistor to – 2 V.

The marketing status values are defined as follows:
ACTIVE: Product device recommended for new designs.
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in
a new design.
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.
OBSOLETE: TI has discontinued the production of the device.

Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS) or Green (RoHS & no Sb/Br) - please check
http://www.ti.com/productcontent for the latest availability information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements
for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered
at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame
retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material)
