PI74AVC+16244 2.5V 16-Bit Buffer Driver with 3-State Outputs Product Features Product Description • PI74AVC+16244 is designed for low-voltage operation, VCC = 1.65V to 3.6V PI74AVC+16244 is a non-inverting 16-bit buffer/driver designed for low-voltage 1.65V to 3.6V VCC operation. • True ±24mA Balanced Drive @ 3.3V 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. • Compatible with Philips and T.I. AVC Logic family • IOFF supports partial power-down operation 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 symmetrical active-low output-enable (OE) inputs. • 3.6V I/O Tolerant inputs and outputs • All outputs contain a patented DDC (Dynamic Drive Control) circuit that reduces noise without degrading propagation delay To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup resistor in which the minimum value is determined by the current-sinking capability of the driver. • Industrial operation: –40°C to +85°C • Packaging (Pb-free & Green available): – 48-pin 240-mil wide plastic TSSOP – 48-pin 173-mil wide plastic TVSOP Logic Block Diagram 1OE 1A1 1A2 1A3 1A4 2OE 2A1 2A2 2A3 2A4 08-0291 1 3OE 47 2 46 3 44 5 43 6 1Y1 3A1 1Y2 3A2 1Y3 3A3 1Y4 3A4 48 4OE 41 8 2Y1 40 9 38 11 37 12 4A1 2Y2 4A2 2Y3 4A3 2Y4 4A4 1 25 36 13 35 14 33 16 32 17 3Y1 3Y2 3Y3 3Y4 24 30 19 29 20 27 22 26 23 4Y1 4Y2 4Y3 4Y4 PS8507C 11/06/08 PI74AVC+16244 2.5V 16-Bit Buffer Driver with 3-State Outputs 12345678901234567890123456789012123456789012345678901234567890121234567890123456789012345678901212345678901234567890123456789012123456789012 12345678901234567890123456789012123456789012345678901234567890121234567890123456789012345678901212345678901234567890123456789012123456789012 Maximum Ratings (Above which the useful life may be impaired.
