CD4516BE

Description

The CD4516BE is a high-reliability 4-bit presettable binary up/down counter that integrates four D-type flip-flops with internal gating to function like T-type counters. It features both reset and preset functionality, allowing direct initialization of the counter via dedicated inputs. The device supports positive-edge-triggered counting and enables synchronous cascading through dedicated carry-in and carry-out pins, simplifying expansion to larger bit widths. Operable over a wide 3–18 V supply range and offering reliable operation across a –55 °C to +125 °C temperature span, it’s well-suited for industrial, embedded, and digital logic systems.

Key Features

• 4-bit binary up/down counter with single-element configuration

• Preset and reset inputs for initializing the counter to a specific value

• Synchronous design with internal carry logic for accurate multi-bit counting

• Wide supply voltage range: 3 V to 18 V DC

• Low-power CMOS technology with minimal input currents (≤1 µA at 18 V)

• Medium-speed operation: typical clock frequency around 8 MHz at 10 V

• Operational temperature range: −55 °C to +125 °C

• Available in standard packages: 16-pin DIP, SOP, and TSSOP formats

• Use cases: frequency division, digital event counting, up/down sequence generation, multi-stage synchronous counting
