TRS213
- ESD Protection for RS-232 bus pins
- ±15kV Human-body model (HBM)
- Meets or exceeds the requirements of TIA/EIA-232-F and ITU v.28 standards
- Operates at 5V VCC supply
- Four drivers and five receivers
- Operates up to 120kbit/s
- Low supply current in shutdownmode: 15µA typical
- External Capacitors: 4 × 0.1µF
- Designed to be interchangeable with industry standard ’213 devices
- Latch-up performance exceeds 100mA per JESD 78, class II
The TRS213 device consists of four line drivers, five line receivers, and a dual charge-pump circuit with ±15kV ESD protection pin to pin (serial-port connection pins, including GND). The device meets the requirements of TIA/EIA-232-F and provides the electrical interface between an asynchronous communication controller and the serial-port connector. The charge pump and four small external capacitors allow operation from a single 5V supply. The devices operate at data signaling rates up to 120kbit/s and a maximum of 30V/µs driver output slew rate.
The TRS213 has an active-low shutdown ( SHDN) and an active-high enable control (EN). In shutdown mode, the charge pumps are turned off, V+ is pulled down to VCC, V– is pulled to GND, and the transmitter outputs are disabled. This reduces supply current typically to 1µA. Two receivers of the TRS213 are active during shutdown.
