MAX232CSE+T RS-232 Transceiver
Dual-Drive/Receiver Architecture with On-Chip Charge Pump – The Ideal Choice for Professional Narrow-Body SOIC-16 Serial Level-Shifting Transceivers.
// High-Reliability Dual RS-232 Line Driver & Receiver Portfolio
The Industry-Standard Level Shifting Edge
The MAX232CSE+T represents a premier flagship interface solution for space-constrained, low-power layouts demanding robust RS-232 serial telemetry links. Engineered by Maxim Integrated, this dual line transceiver eliminates the need for bipolar ±12V power rails by utilizing an advanced on-chip charge-pump network. Running flawlessly off a single +5V supply rail, it provides deterministic bidirectional translation pathways between TTL/CMOS logic and RS-232 signal spectrums inside a compact 16-pin SOIC layout framework.
- Dual-channel transmitter & receiver layout supporting independent full-duplex lines
- Internal capacitive charge pumps generating full EIA/TIA-232 voltage levels
- Input hysteresis circuitry providing exceptional noise rejection across long serial connections
Key Performance Advantages
Single +5V Power Supply
Utilizes four external low-cost 1.0 µF capacitors to step up voltages natively, removing complex auxiliary dual-rail power supplies from the board.
120kbps Data Throughput
Guarantees clean serial communication baud rates over industrial cable lengths, fully meeting standard diagnostic bus interface specifications.
Narrow SOIC-16 Package
Housed in a narrow surface-mount package, optimizing real estate density and enabling seamless pick-and-place automation lines.
