DS90LT012ATMF/NOPB

Overview

The DS90LT012ATMF/NOPB is a single CMOS differential line receiver manufactured by Texas Instruments, designed for low-voltage differential signaling (LVDS) applications. It operates within a supply voltage range of 2.7 V to 3.6 V, with a typical operating voltage of 3.3 V and a quiescent current of 9 mA. The device supports data rates up to 400 Mb/s and features an LVDS input interface that converts signals to an LVTTL output. Key electrical parameters include a propagation delay of 3.5 ns, a maximum input voltage of 0 V, and a minimum input voltage of -100 mV. It is housed in a SOT-23-5 surface-mount package and functions reliably across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Converts differential LVDS inputs to single-ended LVTTL outputs for direct interfacing with digital logic.
• Operates on a standard 3.3 V power supply with low quiescent current consumption.
• Supports high-speed data transmission at rates up to 400 Mb/s.
• Utilizes a compact five-pin SOT-23 package suitable for space-constrained designs.

Applications

• Point-to-point serial communication links requiring LVDS to LVTTL translation.
• Industrial control systems utilizing differential signaling over noisy environments.
• Embedded systems connecting microcontrollers to peripheral devices via LVDS interfaces.

Procurement Notes

Verify the component authenticity by checking the manufacturer marking against the official datasheet specifications. Confirm the package type is SOT-23-5 and the suffix indicates lead-free construction. Ensure the operating temperature range meets the specific environmental requirements of the target application before finalizing procurement decisions.

Selection Notes

Select this component when a single-channel receiver is needed to bridge LVDS sources with LVTTL destinations. It is appropriate for designs requiring moderate data rates up to 400 Mb/s. Consider the SOT-23-5 footprint constraints during PCB layout. Verify that the 3.3 V supply rail aligns with the system power architecture.

Part Context

This part belongs to the DS90LT012A series of LVDS interface integrated circuits. It serves as the receiver counterpart to drivers like the DS90LV017A. The device is part of Texas Instruments' portfolio for low-power, high-speed serial communication solutions, specifically targeting applications where signal integrity is critical but full LVDS termination is not required at the receiving end.

Replacement Considerations

The discontinued DS90LT012ATMF can be directly replaced by the DS90LT012ATMF/NOPB variant. Both parts share identical functional specifications and pinouts, with the NOPB suffix indicating compliance with specific environmental standards.
