Counter Dividers datasheet and documents for MC74ACT161DR2G
Counter Dividers Overview
The MC74ACT161DR2G is a high-speed synchronous modulo-16 binary counter manufactured by onsemi. It features TTL-compatible inputs and operates within a supply voltage range of 4.5 V to 5.5 V. The device includes an asynchronous Master Reset input that overrides all other functions. It supports parallel data loading and counting operations controlled by specific enable inputs. The component is housed in a 16-lead SOIC package.
Counter Dividers Feature Summary
- Synchronous counting and loading capabilities with dedicated control inputs for precise timing management
- Asynchronous Master Reset function that immediately forces outputs low regardless of clock state
- TTL-compatible input thresholds allowing direct interfacing with standard logic families
- High drive output capability supporting both source and sink currents for robust load driving
Counter Dividers Applications
- Programmable frequency dividers
- Synchronous multistage counter configurations
- Digital timing sequence generation
- Event counting circuits
Counter Dividers Procurement Notes
Verify the specific ordering suffix matches the required package type and tape/reel specifications. Confirm RoHS compliance status and lead-free designation as indicated in the manufacturer documentation. Ensure the procurement channel provides valid traceability for the semiconductor components.
Counter Dividers Selection Notes
Select this component when asynchronous reset behavior is required rather than synchronous clearing. Consider the ACT series for TTL compatibility needs at 5V operation. Evaluate the maximum count frequency requirements against the specified AC characteristics for the target operating temperature range.
Counter Dividers Part Context
This part belongs to the MC74AC/ACT161/163 family of synchronous presettable binary counters. It shares functional similarities with the MC74ACT163 but differs in its reset mechanism, utilizing an asynchronous master reset instead of a synchronous one. The DR2G suffix indicates the SOIC-16 package configuration.
