Frequently Asked Questions - MC3487 TEXAS INSTRUMENTS
What is the MC3487?
The MC3487 is a quad differential line driver designed for RS-422 and RS-485 communication. It converts TTL signals to differential outputs for balanced data transmission.
What is the supply voltage range for the MC3487?
The MC3487 operates with a 5 V supply voltage. It is recommended to use a regulated power source within ±5% tolerance.
How many drivers are in the MC3487?
The MC3487 contains four independent differential drivers in a single package, making it suitable for multi-channel applications.
What is the maximum data rate of the MC3487?
The MC3487 supports data rates up to 10 Mbps, depending on cable length and loading conditions.
What is the package type of the MC3487?
The MC3487 is commonly available in an SOIC-16 (small outline integrated circuit) package, with other options such as PDIP.
What is the operating temperature range?
The MC3487 is rated for industrial temperature range from -40°C to +85°C, ensuring reliable performance in harsh environments.
How do I interface the MC3487 with a microcontroller?
Connect the TTL inputs (pins 1, 2, 3, 4) to the microcontroller's logic outputs. The differential outputs (pins 5, 6, 7, 8) go to the bus. Ensure a common ground between devices.
Does the MC3487 support RS-485?
Yes, the MC3487 is also suitable for RS-485 networks if used with appropriate termination resistors and bias. However, it lacks a driver enable pin; for RS-485, consider the MC3486 or similar.
What is the typical power consumption?
Typical power consumption is around 50 mW under nominal conditions, varying with load and data rate.
Is the MC3487 obsolete?
The MC3487 is considered an older device but is still available from Texas Instruments and distributors for legacy designs. For new designs, consider newer alternatives like the SN65HVD3082.
