100352
Low Power 8-Bit Buffer with Cut-Off Drivers
General Description
The 100352 contains an 8-bit buffer, individual inputs (D
n
),
outputs (Q
n
), and a data output enable pin (OEN). A Q out-
put follows its D input when the OEN pin is LOW. A HIGH
on OEN holds the outputs in a cut-off state. 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 impedance reduces
termination power and prevents loss of low state noise
margin when several loads share the bus.
The 100352 outputs are designed to drive a doubly termi-
nated 50
transmission line (25
load impedance). All
inputs have 50 k
pull-down resistors.

Absolute Maximum Ratings
(Note 1)
Recommended Operating
Conditions
Note 1: The "Absolute Maximum Ratings" are those values beyond which
the safety of the device cannot be guaranteed. The device should not be
operated at these limits. The parametric values defined in the Electrical
Characteristics tables are not guaranteed at the absolute maximum rating.
The "Recommended Operating Conditions" table will define the conditions
for actual device operation.
Note 2: ESD testing conforms to MIL-STD-883, Method 3015.

Note 3: The specified limits represent the "worst case" value 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 case" conditions.

Note 5: The propagation delay specified is for single output switching. Delays may vary up to 300 ps with multiple outputs switching.
Note 6: Output-to-Output Skew is defined as the absolute value of the difference between the actual propagation delay for any outputs within the same pack-
aged device. The specifications apply to any outputs switching in the same direction either HIGH-to-LOW (t
OSHL
), or LOW-to-HIGH (t
OSLH
), or in opposite
directions both HL and LH (t
OST
). Parameters t
