The 74HC191N,652 is a presettable synchronous 4-bit binary up/down counter manufactured by NXP Semiconductors. This MSI (Medium Scale Integration) device is designed for high-speed operation with a count rate of up to 39 MHz. It operates across a wide voltage range of 2V to 6V, making it suitable for various digital logic applications.
The counter features synchronous reversible counting and asynchronous parallel load capability, allowing it to be preset to any desired number. It includes count enable control for synchronous expansion and a single up/down control input. The device is housed in a 16-DIP (Dual In-line Package) with through-hole mounting, specified for an operating temperature range of -40°C to 125°C.
Key electrical characteristics include its 4-bit per element structure and synchronous timing. The positive edge trigger type ensures precise counting operations. The 74HC191N,652 is pin-compatible with low-power Schottky TTL (LSTTL) and specified in compliance with JEDEC standard no. 7A.
