Features - Operates With 3-V to 5.5-V VCC Supply - Always-Active Noninverting Receiver Output (ROUT2B) - Low Standby Current: 1 μA Typical - External Capacitors: 4 × 0.1 μF - Accepts 5-V Logic Input With 3.3-V Supply - Inter-Operable With SN65C3238, SN75C3238 - Supports Operation From 250 kbit/s to 1 Mbit/s - RS-232 Bus-Pin ESD Protection Exceeds ±15 k V Using Human-Body Model (HBM) 2 Applications - Battery-powered systems - Personel electronics - Notebooks - Laptops - Palmtop PCs - Hand-held equipment 3 Description The SN65C3243 and SN75C3243 consist of three line drivers, five line receivers, and a dual chargepump 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. In addition, this device includes an always-active noninverting output (ROUT2B), which allows applications using the ring indicator to transmit data while the device is powered down. The device operates at data signaling rates up to 1 Mbit/s and an increased slew-rate range of 24 V/μs to 150 V/μs.
