... Semiconductor's K-Series family modems, allowing system upgrades with a single component change. The 73K324L is ideal for use in free-standing or integral system modem products where full-duplex 2400 bit/s operation with Alternate mode capability is required. Its high functionality, low power consumption, and efficient packaging simplify design requirements and increase system reliability ...

... VDD Write. A low on this informs the 73K324L that data is available on AD0-AD7 for writing into an internal register. Data is latched on the rising edge of WR. No data is written unless both WR and the latched CS are low. The Serial Control mode is provided by tying ALE high and CS low. In this configuration AD7 becomes NOTE: DATA and AD0, AD1 and AD2 become the address only ...
