1 ps8484 03/07/01 product description pericom semiconductor?s pi74avc + series of logic circuits are produced using the company?s advanced submicron cmos technology, achieving industry leading speed. the pi74avc + 16827, is a 20-bit non-inverting buffer/driver designed for 1.65v to 3.6v v cc operation. a buffer/driver is composed of two 10-bit sections with separate output-enable signals. for either 10-bit buffer section, the two output-enable (1oe1 and 1oe2 or 2oe1 and 2oe2 inputs must both be low for the corresponding y outputs to be active. if either output- enable input is high, the output of that 10-bit buffer section are in the high-impedance state. to ensure the high-impedance state during power up or power down, oe should be tied to v cc through a pullup resistor whose minimum value is determined by the current sinking capability of the driver. 1234567890123456789012345678901212345678901234567890123456789012123456789012345678901234567890121234567890123456789012345678901 2123456789012 1 2345678901234567890123456789012123456789012345678901234567890121234567890123456789012345678901212345678901234567890123456789012 12345678901 2 1234567890123456789012345678901212345678901234567890123456789012123456789012345678901234567890121234567890123456789012345678901 2123456789012 pi74avc+16827 2.5v 20-bit buffer/driver with 3-state outputs logic block diagram product features ? pi74avc + 16827 is designed for low voltage operation, v cc = 1.65v to 3.6v true 24ma balanced drive @ 3.3v i off supports partial power-down operation 3.6v i/o tolerant inputs and outputs all outputs contain a patented ddc (dynamic drivecontrol) circuit that reduces noise without degrading propagation delay. industrial operation at ?40c to +85c available packages: ? 56-pin 240 mil wide plastic tssop (a) ? 56-pin 173 mil wide plastic tvsop (k) 1oe 1 1oe 2 1y1 1 2 55 56 1a1 to 9 other channels 2oe 1 2oe 2 2y1 28 15 42 29 2a1 to 9 other channels
