The ADM202JRNZ-REEL7 is an RS-232 transceiver IC from Analog Devices / Maxim Integrated. It integrates two line drivers and two line receivers to provide a complete serial interface between TTL/CMOS logic and RS-232 signals. The device supports full-duplex communication and meets TIA/EIA-232-E and V.28 specifications.
Operating from a single 4.5V to 5.5V supply, the transceiver uses an on-board charge pump to generate the bipolar voltage levels required for RS-232 signaling. Typical supply current is 2.5 mA. The driver output voltage swings to ±9V with a 5V supply, while the receiver inputs accept voltage levels from -30V to +30V. Receiver hysteresis is 400 mV for noise immunity. The device provides a typical data rate of 120 kbps and uses 0.1 µF charge pump capacitors.
The ADM202JRNZ-REEL7 provides 2 kV ESD protection on all pins. It is offered in a 16-lead SOIC (16-SOIC, 0.154" width) surface-mount package and is rated for operation over the commercial temperature range of 0°C to 70°C. The -REEL7 suffix indicates tape-and-reel packaging for automated assembly.
This transceiver is suited for RS-232 interface applications such as computers, peripherals, modems, printers, and instruments. The low operating current and small charge pump capacitors make it suitable for space-constrained designs. The full-duplex configuration allows simultaneous transmit and receive in point-to-point serial links.
The supply voltage range is 4.5V to 5.5V.
It comes in a 16-SOIC (0.154", 3.90mm width) surface-mount package.
The device operates over 0°C to 70°C.
The existing database lists it as RoHS3 compliant; however, compliance is unverified and should be confirmed with the manufacturer.
It integrates 2 drivers and 2 receivers for full-duplex RS-232 communication.
The typical data rate is 120 kbps.
The device provides 2 kV ESD protection on all pins.
