MC74AC161DR2G Description

Short technical summary and product information.

The MC74AC161DR2G from ON Semiconductor is a high-speed synchronous modulo-16 binary counter. It is designed for applications such as programmable dividers and forming synchronous multistage counters. This device offers synchronous counting and loading capabilities, with a typical count rate of 125 MHz as specified in the datasheet, though the product data lists a count rate of 167 MHz.

 

The counter operates over a voltage range of 2V to 6V and has an operating temperature range of -40°C to 85°C. It features an asynchronous Master Reset input that overrides all other inputs, forcing the outputs LOW. The MC74AC161DR2G is available in a 16-SOIC surface mount package.

 

This counter is part of the AC/ACT family, known for its high-speed synchronous expansion capabilities. The outputs can source or sink 24 mA. The 'ACT161 and 'ACT163 variants have TTL compatible inputs. The device is Pb-Free, as indicated by the datasheet.

 

Key features include synchronous operation, a typical count rate of 125 MHz, and outputs that source/sink 24 mA. The package is a standard 16-SOIC, suitable for surface mounting.
