What are the key features of SN75116DRE4?
- Differential line transceiver integrates driver and receiver in one 16-pin SOP package, reducing component count for bidirectional balanced-line links
- Configurable totem-pole outputs allow designers to select output drive mode to suit cable impedance and line termination requirements
- Receiver remains active under driver shutdown, enabling full-duplex monitoring of the bus without powering the transmit stage
- High-impedance 40 µA maximum input current simplifies bus loading calculations in multi-drop RS-422 network designs
What is SN75116DRE4 used for?
SN75116DRE4 serves bidirectional differential serial communication links in industrial automation, test equipment, and legacy RS-422 terminal networks where both transmit and receive functions must share a balanced cable pair. Its configurable output stage adapts to various line impedances from 100 Ω to 120 Ω twisted-pair terminations. The receiver-active-under-shutdown feature allows continuous line monitoring in half-duplex protocols without cycling power to the driver, improving system responsiveness and bus integrity.

Frequently Asked Questions
How does SN75116DRE4 support receiver monitoring while the driver is disabled?
SN75116DRE4 keeps 1 receiver active even when the driver is placed in shutdown mode, allowing the host controller to monitor differential line signals continuously without re-enabling the transmit stage. This feature is critical in half-duplex RS-422 networks where the controller must detect bus contention or incoming data between transmit bursts without losing a receiver active window of even a few microseconds.
What differential output voltage does SN75116DRE4 produce, and how does it relate to EIA-422 noise margins?
SN75116DRE4 produces differential output voltages typically exceeding 2V across a 100 Ω load, well above the 2V minimum driver output specified by EIA-422. This provides at least a 200 mV noise margin above the 1.8V receiver sensitivity threshold, ensuring reliable reception over twisted-pair cables up to several hundred meters at standard RS-422 data rates of 1 Mbit/s to 10 Mbit/s.
In what scenario would configurable totem-pole outputs on SN75116DRE4 simplify PCB design compared to open-collector drivers?
Configurable totem-pole outputs eliminate the external pull-up resistors required by open-collector drivers, saving 2 discrete components per signal line. In a PCB with 4 bidirectional RS-422 pairs, this removes 8 pull-up resistors and reduces power dissipation; at 5V and 1 kΩ pull-ups, each open-collector output wastes 5 mW idle, whereas totem-pole outputs dissipate near-zero static power on terminated 120 Ω lines.
How does SN75116DRE4 in a 16-pin SOP compare to a dual-packaged discrete driver and receiver for a space-constrained RS-422 board?
SN75116DRE4 integrates driver and receiver in a single 16-pin SOP package that measures approximately 10 mm × 4 mm, replacing two separate 8-pin packages occupying at least 16 mm × 4 mm of PCB area. This halves the footprint for each transceiver channel, reduces reflow solder joints by 50%, and consolidates the 40 µA input current load budgeting to a single device characterization sheet.
