MAX3094ECSE+T

MAX3094ECSE+T is Maxim Integrated’s quad RS-232 transceiver. It provides four RS-232 drivers and four receivers, allowing a microcontroller or TTL/CMOS logic to communicate with RS-232 devices. The device uses an on‑chip charge pump to generate the required RS-232 voltage levels from a single supply, simplifying board design. Typical applications include multi‑channel serial interfaces in embedded systems, instrumentation, and PC/terminal links. The ECSE suffix denotes the specific package/temperature variant, and +T indicates tape‑and‑reel packaging. It generally operates from a single 3.3–5 V supply and supports standard RS‑232 data rates (per channel, up to practical Mbps ranges under nominal conditions). Features commonly include TTL/CMOS input thresholds, protection aspects (e.g., ESD), and selectable tri‑state outputs. For exact electrical specs, pinout, and application notes, refer to the MAX3094ECSE+T datasheet on Maxim’s website.
