18-Bit LVTTL/GTLP Universal Bus Transceiver
General Description
The GTLP18T612 is an 18-bit universal bus transceiver
which provides LVTTL to GTLP signal level translation. It
allows for transparent, latched and clocked modes of data
transfer. The device provides a high speed interface for
cards operating at LVTTL logic levels and a backplane
operating at GTLP logic levels. High speed backplane
operation is a direct result of GTLP’s reduced output swing
( 1V), reduced input threshold levels and output edge rate
control. The edge rate control minimizes bus settling time.
GTLP is a Fairchild Semiconductor derivative of the Gun-
ning Transistor logic (GTL) JEDEC standard JESD8-3.
Fairchild's GTLP has internal edge-rate control and is Pro-
cess, Voltage, and Temperature (PVT) compensated. Its
function is similar to BTL or GTL but with different output
levels and receiver thresholds. GTLP output LOW level is
less than 0.5V, the output HIGH is 1.5V and the receiver
threshold is 1.0V.
Ordering Code:
Device also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering code.
