Frequently Asked Questions

How many RS-232 transmit channels does SN75188NSRG4 provide and what standard does it comply with?

SN75188NSRG4 provides 4 independent RS-232 transmit channels with gated inputs, fully compliant with EIA-232-E, TIA-232-E, and V.28 standards, enabling reliable serial data transmission at standard RS-232 voltage levels up to ±15 V.

What package does SN75188NSRG4 use and how does it fit in a serial interface PCB design?

SN75188NSRG4 comes in a 14-pin SOP (PDSO-G14) package, suitable for surface-mount PCB designs. Its small outline form factor allows compact integration of quad RS-232 driving capability on boards with limited space, such as embedded serial communication modules.

When would SN75188NSRG4 be preferred over a single-channel RS-232 driver in industrial designs?

SN75188NSRG4 is preferred when 4 separate RS-232 transmit lines are needed in a single IC, reducing component count and board area compared to using 4 individual single-channel drivers. This is common in multi-port serial data acquisition systems and industrial PLCs requiring RS-232 connectivity on multiple ports.
