description
This octal ECL-to-TTL translator is designed to
provide a efficient translation between a 10KH
ECL signal environment and a TTL signal
environment. This device is designed specifically
to improve the performance and density of
ECL-to-TTL CPU/bus-oriented functions such as
memory-address drivers, clock drivers, and
bus-oriented receivers and transmitters.
Two output-enable pins, OE1 and OE2, are
provided. These control inputs are ANDed
together with OE1 being ECL compatible and OE2
being TTL compatible. This offers the choice of
controlling the outputs of the device from either a
TTL or ECL signal environment.
The SN10KHT5541 is characterized for operation
from 0°C to 75°C.

† Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTE 1: The TTL input voltage ratings may be exceeded provided the input current ratings are observed.

NOTES: A. CL includes probe and jig capacitance.
B. For TTL inputs, input pulses are supplied by generators having the following characteristics: PRR ≤ 10 MHz, Zo = 50 Ω, tr ≤ 2.5 ns,
tf ≤ 2.5 ns.
C. For ECL inputs, input pulses are supplied by generators having the following characteristics: PRR ≤ 10 MHz, Zo = 50 Ω, tr ≤ 0.7 ns,
tf ≤ 0.7 ns.
D. Waveform 1 is for an output with internal conditions such that the output is low except when disabled by the output control. Waveform 2
is for an output with internal conditions such that the output is high except when disabled by the output control.
E. The outputs are measured one at a time with one transition per measurement.

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.
(2)
RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance
do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may
reference these types of products as "Pb-Free".
RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption.
Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of
