Key Features
- Dual differential line receiver with shared strobe input enabling synchronized enable/disable of both channels for bus arbitration and gating applications
- 2 V minimum output swing on each channel, ensuring valid TTL/CMOS logic levels at the receiver output across the full operating temperature range
- Differential input architecture rejects common-mode noise on transmission lines, maintaining signal integrity over long cable runs in industrial environments
Applications
The SN75107BDRE4 is used in industrial RS-422 and balanced differential data links where two independent receiver channels and a shared strobe pin simplify bus enable logic in multidrop networks. It suits long-distance serial communication over twisted-pair cables in factory automation, instrumentation, and motor drive feedback interfaces where common-mode noise rejection is essential. The 14-pin SOIC package accommodates dual-channel reception on the same device, reducing board area and component count in rack-mounted control systems.

Frequently Asked Questions
How does the dual-channel architecture of the SN75107BDRE4 simplify RS-422 receiver design?
By integrating 2 differential receiver channels into one 14-pin SOIC device, the SN75107BDRE4 halves the component count compared to using 2 single-channel receivers. The shared strobe input simultaneously enables or disables both channels with a single logic signal, which is useful for bus-sharing applications where a host must arbitrate access between 2 data lines. Each channel's 2 V minimum output swing ensures clean TTL logic levels at the system controller.
What is the common-mode rejection capability of the SN75107BDRE4, and why does it matter for industrial installations?
The differential input architecture of the SN75107BDRE4 rejects common-mode voltages present on the cable pair, providing immunity to ground potential differences of several volts that commonly occur between equipment in industrial plants. With a maximum high-level input current of only 75 µA, the device presents a light load to the RS-422 driver, allowing up to 32 receiver loads on a single differential bus segment per EIA-422 specification while preserving signal integrity over cable lengths up to 1200 m.
What role does the common strobe input on SN75107BDRE4 play in multi-drop bus designs?
The common strobe input gates both receiver output channels simultaneously, forcing the outputs to a defined state (typically high-impedance or logic low depending on polarity) when deasserted. In a multidrop bus, this allows a central controller to de-select the SN75107BDRE4 receiver while another device drives the same differential pair, preventing bus contention. For 2-channel demultiplexing applications, strobe timing can be as fast as the propagation delay of the device, typically in the range of a few nanoseconds.
How does the 14-pin SOIC package of SN75107BDRE4 aid PCB layout for differential signal routing?
The 14-pin SOIC (JESD-30 R-PDSO-G14) provides 50-mil pin pitch on a body approximately 8.65 mm long, giving enough pin-to-pin distance to route 100-ohm differential pairs directly to input pins without crosstalk between the 2 channels. Placing 100 nF bypass capacitors within 2 mm of the VCC pin and ground plane stitching under the package reduces power supply noise that could otherwise degrade the receiver's differential threshold accuracy.
