Detailed Description

High-speed divide-by-2 logic IC from the onsemi 100LVEL series. Operates at 3.0–3.8 V, supports up to 2.6 GHz count rate, and includes an asynchronous reset. Differential ECL/LVPECL-style I/O for low noise and precision timing. Small 8-SOIC surface-mount package. Industrial temperature range -40°C to +85°C. Part is RoHS non-compliant.

Key Features

Function: Divide-by-2 logic counter/divider

Speed: Up to 2.6 GHz count rate for very high-frequency clocks

Supply: 3.0 V to 3.8 V nominal 3.3 V operation

I/O: Differential ECL/LVPECL-compatible inputs and outputs

Reset: Asynchronous reset for fast and simple control

Triggering: Works on both positive and negative edges

Elements: Single divider, 1 bit per element

Package: 8-SOIC, surface mount

Temperature: -40°C to +85°C

Series: onsemi 100LVEL family

Key Advantages

Very high-speed frequency halving with low added jitter

Differential signaling improves noise immunity and timing accuracy

Simple integration into 3.3 V ECL/LVPECL clock trees

Compact 8-SOIC footprint fits dense boards

Wide industrial temperature support for robust performance

Proven 100LVEL family for consistent, repeatable timing behavior

Packaging

Type: 8-SOIC (JEDEC MS-012)

Material: Molded epoxy plastic body, copper alloy leadframe

Size: Standard SOIC-8 body, width 3.90 mm (0.154"); low profile height

Lead pitch: 1.27 mm; 8 leads total

Mounting: Surface mount

Pin configuration: Differential clock inputs, differential outputs, VCC/GND (or VEE depending on ECL biasing), and asynchronous reset (refer to datasheet for exact pinout)

Thermal characteristics: Designed for high-speed operation; use good PCB copper for heat spreading; ensure airflow and derate power to keep junction temperature within -40°C to +85°C limits

Electrical properties: 3.0–3.8 V supply, differential ECL/LVPECL levels, high toggle rate up to 2.6 GHz

RoHS: RoHS non-compliant (may use SnPb lead finish); check compliance needs before selection

Packaging format: Bulk for this ordering code; other options like tape-and-reel may be available on request
