The SN74176N is a decade counter and latch manufactured by Rochester Electronics. This integrated circuit belongs to the 74 series of TTL logic devices. It combines a decade counter with a 4-bit latch, making it suitable for various counting and display applications.

Applications

• Digital Displays: Used to drive digital displays by counting and latching the count value.
• Frequency Counters: Employed in frequency counters to count the number of pulses in a given time period.
• Timers and Clocks: Utilized in timer and clock circuits for counting time intervals.
• Industrial Control Systems: Integrated into control systems for counting events or time periods.
• Instrumentation: Found in test and measurement equipment for counting and display applications.

Features

• Decade Counter: Counts from 0 to 9 and then resets to 0.
• 4-Bit Latch: Latches the count value for display or further processing.
• Asynchronous Clear Input: Provides an asynchronous clear input to reset the counter to zero.
• Count Enable Inputs: Offers count enable inputs to control the counting process.
• TTL Compatibility: Compatible with other TTL (Transistor-Transistor Logic) devices.
• Through-Hole Package: Available in a through-hole package for easy prototyping and testing.

Benefits

• Simplified Display Design: Combines a counter and latch in a single package, simplifying display design.
• Reduced Component Count: Lowers the number of discrete components required, saving space and cost.
• Versatile Counting and Latching: Offers both counting and latching functions for flexible applications.
• Easy Integration: TTL compatibility allows seamless integration with other TTL logic devices.

Additional Details

The SN74176N operates with a supply voltage of 5V. The counter can be cleared asynchronously using the clear input. The latch is controlled by the latch enable input. This device is commonly used in applications where decimal counting and display are required.
