Logic device/transceiver/encoder

The NCN5150 is a single-chip integrated slave transceiver for two-wire instrumentation bus (M-BUS) slaves and relays. The transceiver provides all the functions required to meet the European standards EN 13757-2 and EN 1434-3 which specify the M-BUS physical layer requirements. It includes programmable power levels up to 2 (SOIC version) or 6 (NQFP version) unit loads and can be used for external circuits through a 3.3V LDO regulator. The NCN5150 provides communication at M-BUS communication speeds up to 38400 baud rate (half-duplex).

The LCX126 contains four independent non-inverting buffers with 3-state outputs. Each output is disabled when the associated output enable (OE) input is low. The input withstand voltage is up to 7V, and it supports the interface from 5V system to 3V system. The 74LCX126 is manufactured using an advanced CMOS process, enabling high-speed operation while maintaining the low power consumption of CMOS.
