概要
Description
MAX1483ESA is a Maxim Integrated (now Analog Devices) serial transceiver in the MAX148x family. It is a high‑speed, low‑power differential bus transceiver used for RS-485/RS-422‑style links. The device combines a driver and a receiver with independent enables (DE and /RE) and 3‑state outputs, suitable for multi‑drop networks. It supports a known idle state via fail‑safe biasing and is designed for industrial/data‑link environments. Typical supply is around 3.3 V (some variants tolerate 5 V), with data rates depending on the exact variant. The ESA suffix generally denotes a RoHS‑compliant package (often an 8‑pin or similar surface‑mount package). Applications include industrial automation, long‑distance serial networks, data acquisition, and PLC interfaces. Pin functions: DI to MCU, RO to MCU, DE/RE controls. For precise electrical specs (Vcc range, input/output voltages, max data rate, propagation delay) consult the MAX1483ESA datasheet and package details.
