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:
7. All typical values are measured at VCC = 3.3V, TA = 25°C.
8. CPD is defined as the value of the internal equivalent capacitance which is derived from dynamic operating current
sumption (ICCD) at no output loading and operating at 50% duty cycle, CPD is related to ICCD dynamic operating
expression: ICCD= (CPD)(VCC)(fIN)+(ICCstatic)
