Interface - Drivers, Receivers, Transceivers

The MC1489ANG4 is a high-speed, low-power, dual differential line receiver designed for use with power-limited data transmission systems. It features wide bandwidth, low propagation delay, and low skew between receivers. The device features two fully independent and wide bandwidth line receivers that are intended for use with an associated transmitting device.

The MC1489ANG4 has an operating voltage range from 2 V to 5.5 V, typical current draw of 18 mA, propagating delay for 2 V of 0.9ns, a bit-error rate (BER) of 0.0004, and a temperature range of -40 ˚C to 125 ˚C. It is powered by a single voltage supply from 2 V to 5.5 V and is capable of operating from a minimum supply voltage of 0.9 V.

Application Field

The MC1489ANG4 is designed to be used in a variety of communications applications, including data transmissions, signal conditioning, signal sensing, signal control, and signal processing. It can also be used in applications such as medical monitoring and diagnostic equipment, embedded controllers, and audio/video data processing. In addition, the device can be used in the industrial automation field, such as the automation of factory floors.

Working Principle

The MC1489ANG4 operates by applying differential inputs to both receivers. The differential inputs allow for the encoding of a single voltage level by sending a unique pair of signals. The first signal sent is the positive (Vin+) and the second signal is the negative (Vin–). The difference between the signals provides a measure of the information content. The device compares the difference between the two inputs and the outputs are activated when the difference exceeds the predetermined thresholds. The outputs are TTL and CMOS compatible.

In addition, the device also contains a differential line receiver, which allows for the detection of greater noise on the data line than a single-ended receiver. The device is also capable of detecting signals at higher frequencies with lower interference. The device incorporates a special input stage clamping circuit, which allows for more accurate voltage linearization than is possible with a single-ended receiver. The device also features a low propagation delay, providing faster data response.

The MC1489ANG4 is capable of driving up to 40 pF loads, allowing for greater data transmission capabilities. The device is also capable of operating at speeds up to 10 Mbps, allowing for data transmission rates that exceed those of other comparable devices. The device also includes an optional output enable function, which allows for the device to be used in applications that require external control of the outputs.

The device is packaged in a 24-lead PDIP and surface mount QFN devices. The QFN devices are RoHS compliant and provide a lead-free, halogen-free design optimized for higher frequency applications. The smaller devices also reduce board space, allowing for a more compact system design.

The MC1489ANG4 offers low-power, high-speed, and wide bandwidth performance, enabling it to be used in a variety of communications applications. The device provides a wide variety of features, including a high speed line receiver, differential output driver, low power operation, and a wide operating voltage range. The device also has a very small form factor, allowing for a more compact design.

Overall, the MC1489ANG4 is an ideal choice for anyone looking for a high-performance, low-power, line receiver for use in data transmission systems. The device provides excellent performance, wide bandwidth, low power operation, and an array of additional features that make it well-suited for use in a wide variety of applications.
