Incremental Single Axis Counters - LSI-LS7166A

The LS7166A is a CMOS, 24-bit counter that can be programmed to operate in several different modes. The operating mode is set up by writing control words into internal control registers. There are three 6-bit and one 2-bit control registers for setting up the circuit functional characteristics. In addition to the control registers, there is a 5-bit output status register (OSR) that indicates the current counter status. The IC communicates with external circuits through an 8-bit three state I/O bus. Control and data words are written into the LS7166A through the bus. In addition to the I/O bus, there are a number of discrete inputs and outputs to facilitate instantaneous hardware based control functions and instantaneous status indication. Note: This series has a minimum purchase requirement of 10 pieces, regardless of stock.

The LSI-LS7166A Series is now LTSOH (Limited to Stock on Hand)
