The MC100ELT21DT is a quad differential line receiver that accepts AC-coupled, differential inputs. The logic level translator is derived from the same design as the popular MC100ELT20 ordered-delta gate. It provides multiple signals that are either low or high, depending on the differential input signals. The MC100ELT21DT also provides a differential input capability and can be used in applications where differential inputs are necessary or desired. The MC100ELT21DT is often used to convert 0.2V-5V low level differential input signals to high-level logic-level signals that can be used by digital logic circuits.

Applications for the MC100ELT21DT include signal-reception and data communications. For example, the MC100ELT21DT can be used to convert low level differential signals from laser diodes, sensors, and other transducers, to high-level logic-level signals that can interface with other electronics. It can also be used in signal-reception and communications applications, such as Ethernet and other serial data-transmission systems, to convert low-level differential analog signals to high-level logic-level signals for use with digital logic circuits.

The MC100ELT21DT is a 4-channel line receiver that employs a novel logic-level translating design. The logic level of the differential inputs can be shifted using an adjustable input threshold to conform to the logic levels required by the output. This allows the MC100ELT21DT to operate effectively over a wide range of input signal levels and voltages. The MC100ELT21DT also reduces noise and over-voltage susceptibility by adjusting the input threshold (common mode voltage).

The MC100ELT21DT offers two functional blocks to provide robust logic-level translation and signal-reception capabilities: Driver and Receiver. The Driver circuit converts the input signal to either a high or low level. The Receiver circuit converts the low-level signal back to its original high-level state. The Driver circuit is an optimized design that uses charge-pumping and distributed capacitance to shift the input signal\'s logic level.

The MC100ELT21DT also features a high-speed differential input for improved signal-reception. This input is buffered to reduce noise sensitivity, and it has hysteresis to reduce jitter on the output. The MC100ELT21DT has an output enable (OE) input, which allows the input signals to be enabled or disabled to reduce power consumption or eliminate false signals. Additionally, the MC100ELT21DT has an open-drain output for connecting with pull-up/pull-down resistors for voltage-level translation.

The MC100ELT21DT is an ideal solution for applications that require logic-level translation, signal-reception, and noise reduction. The MC100ELT21DT requires only a single supply voltage and provides four differential inputs and outputs. The flexibility of the MC100ELT21DT makes it an ideal choice for applications that require cost-effective and reliable level shifting.
