Thông Tin Sản Phẩm
Tổng Quan Sản Phẩm
MAX3232CDR is a 3V to 5.5V multichannel RS-232 line driver and receiver with ±15KV ESD protection. This device consists of two line drivers, two line receivers, and a dual charge-pump circuit with ±15kV ESD protection terminal to terminal (serial-port connection terminals, including GND). This device meets the requirements of TIA/EIA-232- F and provides the electrical interface between an asynchronous communication controller and the serial-port connector. The charge pump and four small external capacitors allow operation from a single 3V to 5.5V supply. The devices operate at data signalling rates up to 250kbit/s and a maximum of 30V/μs driver output slew rate. Applications include industrial PCs, wired networking, data centre and enterprise networking, battery-powered systems, PDAs, notebooks, laptops, palmtop PCs, hand-held equipment.
- RS-232 bus-terminal ESD protection exceeds ±15KV using human-body model (HBM)
- Meets or exceeds the requirements of TIA/EIA-232-F and ITU V.28 standards
- Operates with 3V to 5.5V VCC supply, operates up to 250Kbit/s
- Two drivers and two receivers, low supply current is 1mA max
- External capacitors: 4 × 0.1μF, accepts 5V logic input with 3.3V supply
- Short-circuit output current is ±35mA typ at (VCC = 5.5V, VO = 0V)
- Output resistance is 10Mohm typ at (VCC, V+, and V– = 0V, VO = ±2V)
- 300ns typ propagation delay time, low- to high level output at (CL = 150pF)
- Operating free air temperature range from 0°C to 70°C
- 16-pin SOIC package
Cảnh Báo
This device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
