Device Overview:

️· Type: Dual 4-bit Binary Ripple Counter. It effectively combines two independent 4-bit binary counters into a single IC.
️· Logic Family: Fast Schottky TTL (74F series). This indicates a relatively high-speed logic family.
️· Key Features:
- Synchronous (ripple) operation – the carry-out of one counter stage triggers the next.
- Master Reset (MR) – provides a way to reset both counters simultaneously.
- Clock Input (CPn) – controls the timing of the counters.
- Q outputs (Q0-Q3 for each counter) – provide the binary count output.

Electrical Characteristics (Highlights):

️· Supply Voltage: Typical 5V.
️· Input Logic Levels: TTL compatible.
️· Propagation Delay: Relatively fast due to the 74F series (a few nanoseconds).
️· Maximum Clock Frequency: Up to 130 MHz (varies based on test conditions).
️· Power Dissipation: Typical for a TTL IC (varies with frequency and load).

Pinout & Packaging:

️· Available in DIP14 (standard dual in-line package) and SO14 (small outline package).

Applications:

️· Frequency division
️· Event counting
️· Binary sequencing
️· Digital systems where simple counting or timing is needed.

Important Notes:

️· Data Sheet Status: This document is a full data sheet.
️· Limiting Values: Absolute maximum ratings are provided. Exceeding these can damage the device.
️· Life Support Disclaimer: This device is *not* intended for use in life support systems.
