Overview
The DG309BK is a high-speed, low-power CMOS analog switch manufactured by Harris Corporation. It features a single SPDT (Single Pole Double Throw) configuration with one common input and two complementary outputs. The device operates from a single supply voltage ranging from 4.5V to 20V or dual supplies of ±2.25V to ±10V. Key electrical parameters include an on-resistance of typically 10 ohms and a channel-to-channel matching of 0.5 ohms. It supports a continuous current of 25mA per channel and offers low leakage current. The package is a standard 8-pin DIP.
Feature Summary
- Provides reliable signal routing through a single SPDT switching architecture
- Ensures signal integrity via low on-resistance and tight channel matching
- Supports flexible power configurations for both single and dual supply systems
Applications
- Multiplexing in data acquisition systems
- Signal routing in test and measurement equipment
- Audio and video signal switching applications
Procurement Notes
Verify the manufacturer origin carefully as Harris Corporation's semiconductor assets were acquired by Intersil and subsequently by Renesas. Ensure the component matches the specific 'BK' suffix requirements for packaging or temperature grade. Confirm authenticity through authorized distributors due to potential legacy stock variations.
Selection Notes
Select this component when a single analog switch with SPDT functionality is required. Consider the operating voltage range and on-resistance specifications relative to the signal amplitude. Evaluate thermal dissipation if driving currents approach the 25mA limit. Compare against modern equivalents if long-term availability is a primary constraint.
Part Context
This component belongs to the family of high-performance analog switches originally developed by Harris Semiconductor. These devices are designed for precision applications requiring low distortion and fast switching speeds. The product line has been integrated into broader portfolios following corporate acquisitions, maintaining its role in signal conditioning circuits.
