LATCHES / REGISTERED DRIVERS<br />
Features and benefits<br />
4 Improved synchronous operation, with reduced signal<br />
loads, elimination of timing delays and waveform distortion<br />
4 Mixed 3.3/5 V applications<br />
4 Reduced board space<br />
4 Low-cost interface solutions<br />
4 Improved signal integrity in complex layouts<br />
4 Wide range of supply voltages<br />
4 Low propagation delay<br />
4 Low-power CMOS<br />
4 Optional overvoltage-tolerant inputs, source termination,<br />
low input threshold<br />
Applications<br />
4 Memory controllers<br />
4 Backplane interfaces<br />
