SN74GTLP817
GTLP-TO-LVTTL 1-TO-6 FANOUT DRIVER
SCES285E – OCTOBER 1999 – REVISED APRIL 2005
This device is fully specified for hot-insertion applications using Ioff and power-up 3-state. The Ioff circuitry
disables the outputs, preventing damaging current backflow through the device when it is powered down. The
power-up 3-state circuitry places the outputs in the high-impedance state during power up and power down,
which prevents driver conflict.
This device features adjustable edge-rate control (ERC). Changing the ERC input voltage between GND and VCC
adjusts the B-port output rise and fall times. This allows the designer to optimize system data-transfer rate and
signal integrity to the backplane load. ERC automatically is selected to the same speed as alternate source
1-to-6 fanout drivers that use pin 18 for 3.3-V or 5-V VCC.
When VCC is between 0 and 1.5 V, the device is in the high-impedance state during power up or power down.
However, to ensure the high-impedance state above 1.5 V, the output-enable (OE) input should be tied to VCC
through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the
driver.

FUNCTIONAL DESCRIPTION
The SN74GTLP817 is a fanout driver providing LVTTL-to-GTLP translation and GTLP-to-LVTTL translation in the
same package.
The LVTTL-to-GTLP direction is a 1-to-2 fanout driver with a single output enable (OEAB).
The GTLP-to-LVTTL direction is a 1-to-6 fanout driver with a single output enable (OEBA).
Data polarity is inverting for both directions.
