The MAX14819ATM+T is a high-speed, 3.3V ±5% CMOS transceiver for Automatic Meter Reading (AMR), wireless service interface, wireless local loop (WLL) and control communication systems. The device transmits differential signals, such as RS-485 /RS-422. It provides as much as 7.5 kV of ESD protection on all AS, DE, DI, and DO pins. This device is designed to operate with two different 3.3 V power supplies to comply with AMR, WLL, and control communication systems. The MAX14819ATM+T provides improved noise immunity and enhanced common-mode noise suppression. It also provides excellent EMI control, allowing peaceful coexistence with wireless devices.

The MAX14819ATM+T is designed to interface between a microcontroller\'s logic signals and communications lines. The device either acts as a receiver or driver depending on the logic level at the direction control (DIR) pin.The MAX14819ATM+T continuously monitors the logic level at the DIR pin to determine which logic state to output. The device converts differential logic signals from the microcontroller to single-ended signals for the communications line.

The MAX14819ATM+T features a low-power shutdown mode when VCC is applied and the shutdown input is High. This mode reduces power consumption to less than 5 μA. A TTL LOW level applied to the shutdown input will allow the device to operate and receive signals from a communications line, without transmiting signals. When the shutdown pin is set to HIGH, the MAX14819ATM+T will automatically enter the low-power shutdown mode. It will also enter the low-power shutdown mode if the communications line is in standby mode.

The MAX14819ATM+T comes with an integrated filter module which allows it to reject high-frequency noise. The device also has a low-noise TSSOP package with pinouts compatible with standard transceivers, as well as ESD and surge protection.

The MAX14819ATM+T is well suited for its application in Automatic Meter Reading (AMR)/Wireless Service Interface (WSI) systems, Wireless Local Loop (WLL) systems and Control Communication LED Driver systems. It is a great choice for applications in harsh industrial environments where EMI immunity, ESD protection and surge protection are top concerns. The versatility of the device make it a cost effective solution for AMR/WSI solutions. Its ease of use, combined with its integrated filter module and advanced noise immunity, also make it a great choice for applications in WLL and Control Communication LED Driver systems.

In summary, the MAX14819ATM+T is an excellent transceiver which is well suited for use in a wide range of industrial applications, such as Automatic Meter Reading (AMR), Wireless Service Interface (WSI), Wireless Local Loop (WLL) and Control Communication LED Driver systems. It provides excellent EMI immunity, ESD protection and surge protection. Its integrated filter module, low-power shutdown mode and advanced noise immunity make it an ideal choice for the aforementioned applications.
