Overview
The DS2004CM is a quad differential line receiver manufactured by National Semiconductor, now part of Texas Instruments. It operates within a supply voltage range of 3V to 5.5V and features four independent receivers in a 16-pin plastic DIP package. The device complies with EIA/TIA-232-F and ITU-T V.28 standards for RS-232 communication. It provides high noise immunity with typical input hysteresis of 1.2V at 5V operation. The component supports data rates up to 120kbps and includes internal pull-up resistors on the outputs to ensure a logic high state when inputs are open.
Feature Summary
- Integrates four independent differential receivers for RS-232 signal conversion
- Provides enhanced noise immunity through built-in input hysteresis
- Features internal output pull-up resistors to maintain defined logic states during idle conditions
Applications
- RS-232 serial communication interfaces in industrial equipment
- Data acquisition systems requiring robust signal reception
- Modem interface circuits in telecommunications hardware
Procurement Notes
Verify the manufacturer origin as National Semiconductor or Texas Instruments depending on production era. Confirm the package type is 16-pin PDIP. Check for specific suffixes that may indicate temperature range or lead-free compliance. Ensure the datasheet matches the EIA/TIA-232-F specification requirements for your design.
Selection Notes
Select this component when designing multi-channel RS-232 receivers requiring high noise tolerance. Compare against single-receiver alternatives if only one channel is needed to save board space. Consider the operating temperature range and supply voltage compatibility with your system logic levels before finalizing the choice.
Part Context
This component belongs to the DS2000 series of RS-232 transceivers developed by National Semiconductor. The series includes drivers, receivers, and transceiver combinations. The DS2004CM specifically addresses the need for multiple receiver channels in a single package, simplifying circuit design for complex serial communication applications compared to using discrete components.
