Description

The ST207E is a 5 driver and 3 receiver devices designed for RS-232 and V.28 communications in harsh environments. Each transmitter output and receiver input is protected against ±15KV electrostatic discharge (ESD) shocks. The drivers and receivers of the ST207E meet all EIA/TIA- 232E and CCITT V.28 specifications at data rates up to 120Kbps, when loaded in accordance with the EIA/TIA-232E specification.
The ST207E operates with four 0.1µF capacitors. It came in 24-pin SO and TSSOP packages.

Specifications and features

■ ESD protection for RS-232 i/o pins: ±15 kV human body model
■ 230kbps data rate
■ Guaranteed slew rate 3V/ms (min)
■ Operates from a single 5V power supply
■ Packaged in SO-24, SSO-24 and TSSOP24

Application Scenarios

The ST207E is designed for use in harsh environments where electrostatic discharge is a concern. It is commonly used in RS-232 and V.28 communications in industrial control systems, point-of-sale (POS) systems, and other applications where reliable data transfer is critical.

Comparison

• Protection against ±15KV electrostatic discharge (ESD) shocks on each transmitter output and receiver input
• Meets all EIA/TIA- 232E and CCITT V.28 specifications at data rates up to 120Kbps when loaded appropriately
• Guaranteed slew rate of 3V/ms (min)
• Packaged in SO-24, SSO-24, and TSSOP24 for maximum compatibility

• May not be necessary for applications that do not require protection against ESD
• May not be suitable for applications requiring higher data rates
• Requires four 0.1μF capacitors for operation
