Logic Block Diagram
Product Description
Pericom Semiconductor’s PI74LVTC series of logic circuits are
produced using the Company’s advanced CMOS technology,
achieving industry leading speed.
The PI74LVTC16244 is a non-inverting 16-bit buffer and line
driver designed for low-voltage 2.7V to 3.6V VCC operation, with
the capability of interfacing to the 5V system environment. This
buffer/driver is designed specifically to improve both the perfor-
mance 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.
When VCC is between 0 to 1.5V during power up or power down,
the device is in the high-impedance state. To ensure the high-
impedance state above 1.5V, OE 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.
The device fully supports live-insertion with its Ioff and power-up/
down 3-state. The Ioff circuitry disables the outputs when the
power is off, preventing the backflow of damaging current through
the device. Power-up/down 3-state places the outputs in the high-
impedance state during power up or power down, preventing driver
conflict.

Notes:
Stresses greater than those listed under MAXIMUM RATINGS may
cause permanent damage to the device. This is a stress rating only and
functional operation of the device at these or any other conditions above
those indicated in the operational sections of this specification is not
implied. Exposure to absolute maximum rating conditions for extended
periods may affect reliability.
1. Input negative-voltage and output voltage ratings may be exceeded if the
input and output clamp current ratings are observed.
2. This value is limited to 6.5V maximum.
3. The package thermal impedance is calculated in accordance with JESD
51.
