HLF 74HC191 Presettable Synchronous 4-Bit Binary Up/Down Counter – DIP16 | High-Speed CMOS Logic | 2V–6V, -40°C to +85°C | Through-Hole Package

The HLF 74HC191 is a presettable synchronous 4-bit binary up/down counter built using high-speed CMOS (HC) technology. It features synchronous counting, parallel load, and up/down control, making it suitable for frequency division, digital timing, and event counting applications.

The device can be preset to any desired binary value through its parallel load inputs, and the synchronous up/down control allows precise counting in either direction. Operating at 2V–6V with a temperature range of -40°C to +85°C, the DIP16 package ensures low power consumption, high-speed operation, and robust performance for industrial, embedded, and educational designs.
