GTL Logic
GTL (Gunning Transceiver Log-
ic) provides high speed, low power
consumption, and cost-effective in-
tegration for PC, workstation, and
communication systems running at
50 to 100 MHz. Capable of run-
ning from either a 5V or 3V sup-
ply, it provides an easy migration
to high-performance/low-voltage
operation.
Process, Voltage, and Tempera-
ture (PVT) compensated active
GTL edge rate control can be ei-
ther fixed or pin programmable for
precise, consistent edge rates. The
result is clean, consistent system
performance with enhanced noise
immunity.
Since V
OL
does not vary signifi-
cantly with changes in output load,
GTL provides predictable, low
skew for improved system speed.
National has further optimized this
characteristic with its GTLp
(GTLplus) options. Using an opti-
mized GTLplus device yields lower
skew for even greater system
performance.
National’s first introductions will
be a GTL and GTLp Universal Bus
Transceiver. This function emulates
most logic functions, reducing the
need to stock multiple part num-
bers. Both the TTL and GTL ports
can be configured as transparent,
latched, or clocked.

LIFE SUPPORT POLICY
NATIONAL’S PRODUCTS ARE NOT AUTHORIZED FOR USE AS CRITICAL COMPONENTS IN LIFE SUPPORT
DEVICES OR SYSTEMS WITHOUT THE EXPRESS WRITTEN APPROVAL OF THE PRESIDENT OF NATIONAL
SEMICONDUCTOR CORPORATION. As used herein:
1. Life support devices or systems are devices or
systems which, (a) are intended for surgical implant
into the body, or (b) support or sustain life, and whose
failure to perform, when properly used in accordance
with instructions for use provided in the labeling, can
be reasonably expected to result in a significant injury
to the user.
2. A critical component is any component of a life
support device or system whose failure to perform can
be reasonably expected to cause the failure of the life
support device or system, or to affect its safety or
effectiveness.
