Description
The HEF4520B is a dual 4-bit internally synchronous binary counter with two clock inputs (nCP0 and nCP1), buffered outputs from all four bit positions (nQ0 to nQ3) and an asynchronous master reset input (nMR).
Features
- Tolerant of slow clock rise and fall times.
- Fully static operation.
- 5 V, 10 V, and 15 V parametric ratings.
- Wide supply voltage range from 3.0 V to 15.0 V.
- CMOS low power dissipation.
- High noise immunity.
- Standardized symmetrical output characteristics.
- Complies with JEDEC standard JESD 13-B.
- ESD protection:.
- HBM: ANSI/ESDA/JEDEC JS-001 class 2 exceeds 2000 V.
- CDM: ANSI/ESDA/JEDEC JS-002 class C3.
