SLLS825B - AUGUST 2007 - REVISED JUNE 2021 TRSF3232E 3-V TO 5.5-V Two-Channel RS-232 1-Mbit/s Line Driver and Reciever with ±15-k V IEC ESD Protection in Small Package 1 Features - Operates with 3-V to 5.5-V VCC supply - Operates up to 1 Mbit/s - Low supply current: 300 μA typical - External capacitors: 4 × 0.1 μF - Accept 5-V logic input with 3.3-V supply - Latch-up performance exceeds 100 m A Per JESD 78, class II - ESD protection for RS-232 pins - ±15-k V Human-Body Model (HBM) - ±15-k V IEC 61000-4-2 air-gap discharge - ±8-k V IEC 61000-4-2 contact discharge - Available in near chip scale QFN (3mmx3mm) package (85% smaller than SOIC-16) 2 Applications - Industrial PCs - Wired networking - Data center and enterprise puting - Battery-powered systems - PDAs - Notebooks - Palmtop PCs - Hand-held equipment DIN1 10 DIN2 3 Description The TRSF3232E consists of two line drivers, two line receivers, and a dual charge-pump circuit with ±15-k V ESD protection pin to pin (serial-port connection pins, including GND). This device provides the electrical interface between an asynchronous munication controller and the serial-port connector. The charge pump and four small external capacitors allow operation from a single 3-V to 5.5-V supply. The TRSF3232E operates at data signaling rates up to 1 Mbit/s and a driver output slew rate of 14 V/μs to 150...
