1 ps8525 02/28/01 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 16-bit pi74avc+16334 universal bus driver is designed for 2.3v to 3.6v vcc operation. data flow from a to y is controlled by output enable (oe). the device operates in the transparent mode when le is low. when le is high, the a data is latched if clk is held at a high or low logic level. if le is high, the a-data is stored in the latch/flip- flop on the low-to-high transition of clk. when oe is high, the outputs are in the high-impedance state. to ensure the high-impedance state during power up or power down, 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. 1234567890123456789012345678901212345678901234567890123456789012123456789012345678901234567890121234567890123456789012345678901 2123456789012 1 2345678901234567890123456789012123456789012345678901234567890121234567890123456789012345678901212345678901234567890123456789012 12345678901 2 2.5v 16-bit universal bus driver with 3-state outputs logic block diagram product features ? pi74avc+16334 is designed for low voltage operation, v cc = 1.65v to 3.6v ? true 24ma balanced drive @ 3.3v ? compatible with philips and t.i. avc logic family ?i off supports partial power-down operation ? 3.6v i/o tolerant inputs and outputs ? meets pc133 sdram registered dimm specifications ? all outputs contain a patented ddc (dynamic drive control) circuit that reduces noise without degrading propagation delay ? industrial operation at ?40c to +85c ? available packages: ? 48-pin 240-mil wide plastic tssop (a) ? 48-pin 173-mil wide plastic tvsop (k) pi74avc+16334 to 15 other channels clk le a1 47 25 48 oe 1 1d c1 clk y1 2
