The DMA controller is a state-driven address and controlsignal generator, which permits data to be transferreddirectly from an l/0 device to memory or vice versa withoutever being stored in a temporary register. This can greatlyincrease the data transfer rate for sequential operations,compared with processor move or repeated stringinstructions. Memory-to-memory operations requiretemporary internal storage of the data byte betweengeneration of the source and destination addresses, somemory-to-memory transfers take place at less than half therate of l/0 0perations, but still much faster than with centralprocessor techniques. The maximum data transfer ratesobtainable with the 82C237 are shown in Figure l.

Hot-Swap Input CircuitryThe MAX3465/MAX3468 enable inputs feature hot-swapcapability. At the input there are two NMOS devices, M1and M2 (Figure 4). When VcC ramps from 0, an internal15Us timer turns on M2 and sets the SR latch, whichalso turns on Ml. Transistors M2, a 2mA current sink,and Ml, a 100pA current sink, pull DE to GND through a5.6kQ resistor. M2 is designed to pull DE to the disabledstate against an external parasitic capacitance up to100pF that can drive DE high. After 15Us, the timerdeactivates M2 while Ml remains on, holding DE lowagainst three-state leakages that can drive DE high. M1remains on until an external source overcomes therequired input current. At this time, the SR latch resetsand Ml turns off. When Ml turns off, DE reverts to astandard, high-impedance CMOS input. Whenever VCCdrops below lV, the hot-swap input is reset.
