Overview
The DS3487MX/NOPB is a quad TRI-STATE line driver compliant with EIA RS-422 standards. It operates on a 5V supply voltage ranging from 4.75V to 5.25V, consuming 80mA of active power supply current. The device features four independent drivers with typical propagation times of 10ns and output rise/fall times under 15ns. It utilizes a 16-pin SOIC package and supports an operating temperature range from 0°C to +70°C.
Feature Summary
- Four independent TRI-STATE outputs for balanced voltage digital interface circuits
- TTL compatible inputs with PNP buffering to minimize input loading
- Fast propagation times and output transition speeds
Applications
- Balanced voltage digital interface circuits
- RS-422 communication systems
- Industrial control networks
Procurement Notes
Verify the LIFEBUY status before procurement as production has ceased. Confirm the specific SOIC-16 package variant matches design requirements. Ensure compliance with RoHS and halogen-free specifications. Validate that the 0°C to +70°C operating range suits the target environment. Check for obsolescence warnings in the latest datasheet revision.
Selection Notes
Select this component when a quad RS-422 driver with TRI-STATE capability is required. Ensure the system operates within the specified 4.75V to 5.25V supply range. Verify that the 16-pin SOIC footprint fits the PCB layout. Consider the 80mA active current consumption for power budgeting. Confirm compatibility with TTL logic levels for input signals.
Part Context
This part belongs to the DS3487 series of RS-422 interface integrated circuits manufactured by Texas Instruments. It serves as a direct replacement for legacy components like the MC3487 and DS8924 due to pin compatibility. The device is designed for reliable data transmission in industrial environments requiring differential signaling.
Replacement Considerations
The DS3487MX/NOPB is pin-compatible with the MC3487 and DS8924. Designers should verify electrical characteristics match their existing circuit requirements when substituting these parts. No functional changes are expected due to the identical pinout configuration.
