These 16-bit buffers/drivers are designed specifically for low-voltage (3.3-V) V operation, but with the
CC
capability to provide a TTL interface to a 5-V system environment.
The devices can be used as four 4-bit buffers, two 8-bit buffers, or one 16-bit buffer. The devices provide
noninverting outputs and complementary output-enable (OE and OE
) inputs.
When V
is between 0 and 1.5 V, the devices are in the high-impedance state during power up or power down.
CC
However, to ensure the high-impedance state above 1.5 V, OE
should be tied to V through a pullup resistor
CC
and OE should be tied to GND through a pulldown resistor; the minimum value of the resistor is determined by
the current-sinking/current-sourcing capability of the driver.
Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level.
