The CD74HC163E is a high-speed CMOS logic 4-bit binary counter designed and manufactured by Texas Instruments. This integrated circuit is part of the HC family, which signifies that it combines the high noise immunity of CMOS with the low power consumption and high-speed performance of TTL logic. The CD74HC163E is tailored for use in a wide array of applications, ranging from digital systems to general-purpose counting, due to its versatile features and reliable performance.

Key Features

• Synchronous Counting: The CD74HC163E operates on synchronous counting, which ensures that the state of the counter advances on the rising edge of the clock pulse. This characteristic allows for precise timing and control in digital systems.
• Asynchronous Reset: An asynchronous master reset input is provided, which sets all outputs to zero when a high level is applied, regardless of the state of the clock input. This feature allows for quick initialization or reset of the counter state.
• Expandable: The counter can be easily expanded by cascading multiple CD74HC163E devices. This is facilitated by the overflow or carry output, which can be used to trigger the count input of the next counter in the series.
• Wide Operating Voltage Range: It operates within a voltage range of 2V to 6V, making it compatible with a variety of logic levels and suitable for interfacing with both TTL and CMOS technologies.
• High Output Current: This device can drive up to 5.2mA at the output, allowing it to directly drive LEDs or other visual indicators in a circuit.
