LTC488CN#PBF

Drivers, Receivers, Transceivers Overview

The LTC488CN#PBF is a low-power quad RS-485 line receiver manufactured by Analog Devices Inc. It operates on a single 5V supply with a specified range of 4.75V to 5.25V and draws a typical supply current of 7mA. The device features four differential receivers with three-state outputs, designed for multipoint data transmission in RS-485 applications. It supports an extended common mode range from -7V to +12V, allowing up to ±7V ground difference between devices. Key electrical parameters include a typical propagation delay of 28ns, input hysteresis of 60mV, and ESD protection up to 2kV. The component is housed in a 16-lead plastic DIP package and functions within a commercial temperature range of 0°C to 70°C.

Drivers, Receivers, Transceivers Feature Summary

• Low power CMOS design significantly reduces consumption compared to bipolar counterparts while maintaining ruggedness against overload and ESD damage.
• Fail-safe feature guarantees a high output state when inputs are left open or floating.
• Extended common mode range permits significant ground differences between devices on the bus.
• Three-state outputs maintain high impedance across the entire common mode range.

Drivers, Receivers, Transceivers Applications

• Multipoint data transmission systems utilizing the RS-485 standard.
• Level translation interfaces between different voltage domains.
• RS-422 compliant communication networks requiring robust line reception.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix to confirm the package type and lead finish. The CN designation indicates a 16-lead Plastic DIP package suitable for through-hole mounting. Ensure the procurement channel provides components with verified lead-free finishes as indicated by the PBF suffix. Cross-reference the manufacturer part number directly with official documentation to avoid counterfeit parts.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring multiple receivers without integrated drivers. It serves as a pin-compatible replacement for the SN75173. Consider the 0°C to 70°C operating temperature range for environmental suitability. Verify that the system requires only receiving functionality, as this part does not include transmitter circuits.

Drivers, Receivers, Transceivers Part Context

This component belongs to the LTC488/LTC489 family of low-power differential bus receivers. The LTC488 variant specifically provides four independent receivers with shared enable controls. It is designed to interface with RS-485 transceivers like the LTC486 or LTC487 in half-duplex configurations. The family emphasizes power savings and noise immunity for industrial communication buses.

Drivers, Receivers, Transceivers Replacement Considerations

The datasheet identifies the SN75173 as a pin-compatible alternative. When substituting, verify that the replacement meets the same electrical specifications regarding common mode range and supply voltage requirements.
