Working Principles

The SN75ALS181NSRG4 is a differential line transceiver that converts TTL/CMOS logic levels to differential outputs. It operates by receiving input signals on the receiver inputs (A1-A4, B1-B4) and converting them into differential outputs (Y1/Y2, Z1/Z2). The device uses internal circuitry to provide high-speed data transmission while consuming low power.
