Product Description
PI74AVC+16244 is a non-inverting 16-bit buffer/driver designed
for low-voltage 1.65V to 3.6V V_CC operation.
The buffer/driver is designed specifically to improve both the
performance and density of 3-state memory address drivers, clock
drivers, and bus-oriented receivers and transmitters.
The device can be used as four 4-bit buffers, two 8-bit buffers, or
one 16-bit buffer. It provides non-inverting outputs and symmetri-
cal active-low output-enable (OE) inputs.
To ensure the high-impedance state during power up or power
down, OE should be tied to V_CC through a pullup resistor in which
the minimum value is determined by the current-sinking capability
of the driver.
