The MAX3226ECAE+T is a multi-channel, low-power ESD-protected CMOS line transceiver. It offers ±15kV ESD protection on all pins, and is ideal for use in portable communication equipment, such as laptops, PDA\'s, and other peripheral devices, where small size and low power are important. The MAX3226ECAE+T is ideal for applications such as interfaces between standard UARTs and RS-232 devices.

The MAX3226ECAE+T features power-saving shutdown, lowpower-sleep mode operation and a low-voltage interface. It contains two independent transceivers, each one featuring independent receive and transmit logic, with the output stage operating from a logic-high latch or logiclow latch configuration. The MAX3226ECAE+T also features adjustable hysteresis, which is used to control the threshold of the receiver.

The MAX3226ECAE+T is designed for low-power applications and has a supply voltage range of 2.5V to 6V. It also allows for 3.3V operation, when the input levels and the output levels are matched, making it the ideal choice for 3.3V applications. The MAX3226ECAE+T is available in 8 and 24 pin SOIC packages, as well as a 4x4mm leadless chip carrier (LCC) package.

The MAX3226ECAE+T can be used in a variety of different applications, including RS-232 interfaces and point-to-point connections. It can be used for high-speed serial communication, allowing up to 921.6 Kbps data rates. The transceiver\'s integrated ESD protection makes it an ideal solution for applications where ESD protection is a critical requirement, such as portable devices.

The MAX3226ECAE+T works by providing an interface between two different logic levels, allowing data to be transmitted and received between devices, while also providing protection against ESD events. The MAX3226ECAE+T can be used to interface between two different logic levels, such as the TIA/EIA-232 levels (±15V) and the TTL level (5V).

At the receiver stage, the MAX3226ECAE+T features a differential input stage with a wide hysteresis range. This low-voltage swing hysteresis provides superior noise rejection, making it ideal for high-speed serial communications. The adjustable hysteresis level also allows the receiver to be optimized for each application. The hysteresis range is adjustable from 2.14V to 7.14V.

At the transmitter stage, the MAX3226ECAE+T provides both 3-state control and low-skew switching. The 3-state control allows the MAX3226ECAE+T to maintain compatibility with both TTL and EIA/TIA-232 interface levels. The low-skew switching ensures that the output signals switch at the same time and with the same rise and fall times. This feature eliminates the need for external equalization.

The MAX3226ECAE+T is the ideal device for many applications, thanks to its high ESD immunity, low-power consumption, wide voltage range and adjustable hysteresis. It is suitable for applications where a low-power, robust line transceiver is needed, such as in data links, RS-232 interfaces and peripheral control applications. The MAX3226ECAE+T works well with other systems, as it is compatible with both TTL and EIA/TIA-232 interface levels.
