Description and Introduction

Presettable synchronous 4-bit binary up/down counter The 74HCT191D is a high-speed CMOS logic device manufactured by Philips (PHI). It is a 4-bit synchronous up/down binary counter with asynchronous reset. Key specifications include:

- **Supply Voltage (VCC):** 4.5V to 5.5V
- **Operating Temperature Range:** -40°C to +125°C
- **Logic Family:** HCT (High-speed CMOS with TTL compatibility)
- **Package:** SOIC-16
- **Counting Modes:** Up and Down
- **Clock Input:** Synchronous
- **Asynchronous Reset:** Yes
- **Output Current:** ±4mA (sink/source)
- **Propagation Delay:** Typically 20ns at 5V
- **Power Dissipation:** Low power consumption, typical of CMOS devices

The 74HCT191D is designed for applications requiring high-speed counting and is compatible with TTL levels, making it suitable for interfacing with TTL logic systems.
