LS7166 Overview
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). There are three 6-bit and one 2-bit control registers for setting up the circuit functional characteristics.
LS7166 Key Features
- Programmable modes are: Up/Down
- DC to 25MHz Count Frequency
- 8-Bit I/O Bus for uP munication and Control
- 24-Bit parator for pre-set count parison
- Readable status register
- Input/Output TTL and CMOS patible
- 3V to 5.5V operation (VDD
- LS7166 (DIP); LS7166-S (SOIC); LS7166-TS24 (24-Pin TSSOP)
- D7) for READ or WRITE when CS = 0. The C/D input selects between the control registers (C/D = 1) and the data registers
