CD4522BMT General Description

CD4522B programmable BCD counter has a decoded "0" state output for divide-by-N applications. In single stage operation the "0" output is tied to the Preset Enable input. The Cascade Feedback allows multiple stage divide-by-N operation without the need for external gating. A HIGH on the Clock Inhibit disables the pulse-counting function. A HIGH on the Master Reset asynchronously resets the divide-by-N operation. The output is presented in BCD format.

The CD4522B-series types are supplied in 16-lead dual-in-line plastic packages (E suffix), 16-lead small-outline packages (M, M96, MT, and NSR suffixes), and 16-lead thin shrink small-outline packages (PW and PWR suffixes).

Key Features

Internally synchronous for high internal and external speeds
Logic edge-clocked design — increments on positive Clock transition or on negative Clock inhibit transition.
100% tested for quiescent current at 20-V
5-V, 10-V, and 15-V parametric ratings
Standard symmetrical output characteristics
Maximum input current of 1 µA at 18 V over full package-temperature range; 100 nA at 18 V and 25°C
Meets all requirements of JEDEC Tentative Standard No. 13B, "Standard Specifications for Description of ’B’ Series CMOS Devices"
Applications:
- Frequency synthesizers
- Phase-locked loops
- Programmable down counters
- Programmable frequency dividers

NOT RECOMMENDED FOR NEW DESIGNS
