LS7166 - 24-BIT QUADRATURE COUNTER

Datasheet Summary

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).

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.
