General Description
The DS16F95A Differential Bus Transceiver is a monolithic integrated circuit designed for bidirectional data communication
on balanced multipoint bus transmission lines. The transceiver conforms to both TIA/EIA-485-A and
TIA/EIA-422-B standards.
The DS16F95A offers improved performance due to the use of L-FAST bipolar technology. The L-FAST technology allows for higher
speeds and lower currents by minimizing gate delay times. The DS16F95A features an extended temperature range and is offered
in a rugged ceramic package.
The DS16F95A combines a TRI-STATE differential line driver and a differential input line receiver, both of which operate from a single 5.0V power supply. The
driver and receiver have an active Enable that can be externally connected to function as a direction control. The driver
differential outputs and the receiver differential inputs are internally connected to form differential input/output (I/O)
bus ports that are designed to offer minimum loading to the bus whenever the driver is disabled or when VCC = 0V. These ports feature wide positive and negative common mode voltage ranges, making the device suitable for multipoint
applications in noisy environments.
The driver is designed to accommodate loads of up to 60 mA of sink or source current and features positive and negative current
limiting for protection from line fault conditions.
The device is offered in a rugged 8–lead Ceramic DIP package and is functional over the extended temperature range of -55
°C to +180 °C.

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR.
The Long Term Failure Rates were calculated
at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress
temperature of 150°C to an application temperature of 55°C.
