STM7E1AR Description

Short technical summary and product information.

The STMicroelectronics STM7E1AR is a specialized analog switch IC designed for E1/T1 signal routing and telecommunications infrastructure. This device offers 7 identical channels, each equipped with main and auxiliary switches. The main switches provide a low on-resistance of typically 2 Ohms, while auxiliary switches have an on-resistance of less than 75 Ohms. The STM7E1AR supports an analog input signal amplitude of up to 6 VPP and operates within a voltage range of ±3.3V.

 

Designed for surface mounting, the STM7E1AR comes in a 64-TQFP package, making it suitable for compact board designs. Its operating temperature range is -40°C to 85°C. The device is controlled by digital inputs and is ideal for applications such as relay replacement, loopback hardware diagnostics, and line card functions. The 64-TQFP (10x10) package ensures efficient integration into various electronic systems.

 

Key features include TTL-compatible digital inputs and a clock frequency of 12MHz. The switch array architecture allows for flexible signal routing between main and spare ports, with the spare port primarily used for test purposes. Proper power supply decoupling is recommended for optimal performance.
