Description and Introduction

asynchronous reset The 74HCT161 is a high-speed CMOS 4-bit synchronous binary counter manufactured by various companies, including Texas Instruments, NXP Semiconductors, and others. It is part of the 74HCT family, which combines the low power consumption of CMOS technology with the high-speed operation of TTL. Key specifications include:

- **Supply Voltage (VCC):** 4.5V to 5.5V
- **Operating Temperature Range:** -40°C to +125°C
- **High-Level Input Voltage (VIH):** 2V (min)
- **Low-Level Input Voltage (VIL):** 0.8V (max)
- **High-Level Output Voltage (VOH):** 4.4V (min) at IOH = -4mA
- **Low-Level Output Voltage (VOL):** 0.1V (max) at IOL = 4mA
- **Maximum Clock Frequency:** 50 MHz (typical)
- **Power Dissipation:** 500 mW (max)
- **Package Options:** DIP-16, SO-16, TSSOP-16

The 74HCT161 features synchronous counting, asynchronous master reset, and parallel load capabilities, making it suitable for various counting and timing applications. It is compatible with TTL levels, ensuring easy integration into existing designs.
