LS7166 - 24-BIT QUADRATURE COUNTER

General Description

The LS7166 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 (see Figure 8).

Key Features

  • Programmable modes are: Up/Down, Binary, BCD, 24 Hour Clock, Divide-by-N, x1 or x2 or x4 Quadrature and Single-Cycle.
  • DC to 25MHz Count Frequency.
  • 8-Bit I/O Bus for uP Communication and Control.
  • 24-Bit comparator for pre-set count comparison.
  • Readable status register.
  • Input/Output TTL and CMOS compatible.
  • 3V to 5.5V operation (VDD - VSS).
  • LS7166 (DIP); LS7166-S (SOIC); LS7166-TS24 (24-Pin TSSOP) - See Figure 1 GENER.
