Description:
The LS7166B is a CMOS, 24-bit counter which can be programmed to operate in several functional modes. The operating modes are set up by writing configuration data into control registers. There are three 6-bit and one 2-bit control registers for configuring the functional modes. In addition to the control registers there is a 5-bit status register which indicates the instantaneous device status. A 24-bit preset register is available for presetting the counter. It also serves as the division factor in the mod-N count mode. The device communicates with a host controller over an 8-bit 3-state bidirectional data bus through read/written operations. In addition, a number of discrete inputs and outputs facilitate instantaneous hardware control functions and instantaneous status indication.
