The NTE4522B is a CMOS programmable divide-by-N 4-bit BCD counter in a 16-lead DIP package. It features a monolithic structure utilizing MOS P-channel and N-channel enhancement mode devices. This device operates as a cascadable down counter with a decoded "0" state output, making it suitable for divide-by-N applications. The clock inhibit input allows for the disabling of pulse counting, while the cascade feedback input facilitates cascading without additional gates. Key specifications include a quiescent current of 5nA at 5V, a supply voltage range of 3V to 18V, and an internally synchronized design that supports high-speed operations. The NTE4522B can handle a counting rate of up to 5 MHz and is capable of driving two low-power TTL loads or one low-power Schottky TTL load. It operates effectively across a temperature range of -55¬8C to +125¬8C, making it suitable for various applications, including frequency synthesizers and phase-locked loops. The device also includes asynchronous preset enable and a master reset function for enhanced control.
