GTL Logic
GTL (Gunning Transceiver Logic) provides high speed, low power
consumption, and cost-effective integration for PC, workstation, and
communication systems running at
50 to 100 MHz. Capable of running from either a 5V or 3V supply, it provides an easy migration
to high-performance/low-voltage
operation.
Since VOL does not vary significantly 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 optimized GTLplus device yields lower
skew for even greater system
performance.
Process, Voltage, and Temperature (PVT) compensated active
GTL edge rate control can be either fixed or pin programmable for
precise, consistent edge rates. The
result is clean, consistent system
performance with enhanced noise
immunity.
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 numbers. Both the TTL and GTL ports
can be configured as transparent,
latched, or clocked.
