TPT3243

3-V to 5.5-V, 1-Mbps Multi-Channel RS-232 Transceiver

Overview

The TPT3243 is ±20-kV IEC61000-4-2 contact ESD protected, 3.0-V to 5.5-V powered transceivers that meet the RS-232 standards for balanced communication. Each receiver converts TIA/RS-232 inputs to TTL/CMOS levels.

The charge pump and external capacitors support the device operating from a single 3.0-V to 5.5-V power supply. The device has an always-active output ROUT2B, which allows applications using the ring indicator to transmit data as the device is powered down.

The auto power-down function supports the ultra-low power mode. As the ONLINE is low and OFF is high, the driver outputs are disabled while the device does not sense a valid RS-232 signal. If OFF is set low, both drivers and receivers (except ROUT2B) are disabled, and the supply current is down to 1 μA.

The devices have a typical threshold of 1.25 V, a typical hysteresis of 0.3 V, and can accept ±25-V inputs. The device operates at data signaling rates up to 1 Mbps. The TPT3243 is available in SOP28, TSSOP28, SSOP28, and QFN5x5-32 packages, and is characterized from −40°C to 125°C.
