Typical Application



Description

The 3PEAK TP32xxN devices are 3.0V to 5.5V RS-232 transmitters/receivers which meet ElA/TIA-232 and V.28/V.24 specifications, even at VCC = 3.0V. Each receiver converts TIA/RS-232-F inputs to TTL/CMOS levels.


The devices have a typical threshold of 1.26V, a typical hysteresis of 0.5V, and can accept ±25V inputs. Data rates greater than 470kbps are guaranteed at worst case load conditions. The devices are fully compatible with 3.3V-only systems, mixed 3.3V and 5.0V systems, and 5.0V-only systems. Additionally, they provide ±15kV ESD protection (IEC61000-4-2 Air Gap and Human Body Model) on transmitter outputs (RS-232 pins).


The TP3232N/TP3222N has two receivers and two transmitters. The TP3222N features a 1μA shutdown mode that reduces power consumption in battery powered portable systems. The TP3222N receivers remain active in shutdown mode, allowing monitoring of external devices while consuming only 1μA of supply current.
