MC14521B Overview
MC14521B 24-Stage Frequency Divider The MC14521B consists of a chain of 24 flip−flops with an input circuit that allows three modes of operation. The input will function as a crystal oscillator, an RC oscillator, or as an input buffer for an external oscillator. Each flip−flop divides the frequency of the previous flip−flop by two, consequently this part will count up to 224 = 16,777,216.
MC14521B Key Features
- All Stages are Resettable

- RC and Crystal Oscillator Outputs Are Capable of Driving External
- Test Mode to Reduce Test Time
- Supply Voltage Range = 3.0 Vdc to 18 Vdc
- Capable of Driving Two Low-Power TTL Loads or One Low-Power
- NLV Prefix for Automotive and Other
