1 / 8 page 1 PS8652A 05/19/03 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. 12345678901234567890123456789012123456789012345678901234567890121234567890123456789012345678901212345678901234567890123456789012123456789012 12345678901234567890123456789012123456789012345678901234567890121234567890123456789012345678901212345678901234567890123456789012123456789012 12345678901234567890123456789012123456789012345678901234567890121234567890123456789012345678901212345678901234567890123456789012123456789012 3.3V 16-Bit Buffer/Line Driver with 3-State Outputs Logic Block Diagram Product Features · Advanced low power CMOS design for 2.7V to 3.6V VCC operation · Supports 5V input/output tolerance in mixed signal mode operation · Function compatible with LVT family of products · Balanced ±24mA output drive · Typical VOLP (Output Ground Bounce) <0.8V at VCC=3.3V, TA=25°C ·Ioff and Power Up/Down 3-State support live insertion · Latch-up performance exceeds 200mA Per JESD78 · ESD protection exceeds JESD 22 - 2000V Human-Body Model (A114-B) - 200V Machine Model (A115-A) · Available Packages (Pb-free available): - 48-pin 240-mil wide plastic TSSOP (A48) - 48-pin 300-mil wide plastic SSOP (V48) · Industrial Temperature: -40°C to +85°C PI74LVTC16244 1OE 1A1 1Y1 1A2 1Y2 1A3 1Y3 1A4 1Y4 3OE 3A1 3Y1 3A2 3Y2 3A3 3Y3 3A4 3Y4 2OE 2A1 2Y1 2A2 2Y2 2A3 2Y3 2A4 2Y4 4OE 4A1 4Y1 4A2 4Y2 4A3 4Y3 4A4 4Y4 43 44 46 47 1 37 38 40 41 48 12 11 9 8 6 5 3 2 32 33 35 36 25 17 16 14 13 26 27 29 30 24 23 22 20 19 |
