Product Overview: 74LVC169PW,118

The 74LVC169PW,118 is a high-performance, low-voltage 4-bit binary synchronous counter designed and manufactured by NXP Semiconductors. This integrated circuit (IC) is part of the LVC family, which is characterized by its low-voltage operation and high-speed interface technology. The device is specifically tailored for use in 3.3V systems but has a tolerant range that allows it to interface with 5V systems, making it highly versatile in mixed-voltage environments.

Key Features

• Counter Type: 4-bit binary synchronous
• Supply Voltage Range: 1.2V to 3.6V, allowing for compatibility with various system voltages
• High Noise Immunity: Ensures stable operation in electrically noisy environments
• 5V Tolerant Inputs: Inputs can handle 5V signals without damage, providing design flexibility
• Low Power Consumption: Ideal for battery-operated and power-sensitive applications
• High-Speed Operation: Capable of operating at frequencies up to 180 MHz at 3.3V
• Output Capability: Can drive up to 50 ohm transmission lines directly
• Package: TSSOP16, a thin shrink small outline package that is space-saving and suitable for automated assembly processes

Functional Description

The 74LVC169PW,118 is a presettable synchronous counter that features an internal carry look-ahead for application in high-speed counting designs. It can be configured as a modulo-16 binary counter or a modulo-10 decimal counter. The counter advances on the low-to-high transition of the clock (CLK) input while the count enable (CE) input is held low. A high on the master reset (MR) input sets all outputs to low, regardless of other inputs. The counter can be preset to a desired value by applying the value to the data inputs (D0 to D3) and taking the parallel load input (PL) low.

Applications

With its robust feature set, the 74LVC169PW,118 is suitable for a wide range of applications, including:

• Industrial control systems
• Automotive electronics
• Data processing
• Instruments and measurement systems
• Telecommunications

Overall, the 74LVC169PW,118 from NXP Semiconductors is a reliable and efficient solution for designers looking to implement synchronous counting in their digital systems, with the added benefit of interfacing with both 3.3V and 5V logic levels.
