Quadruple Differential Line Receiver: Contains four independent receivers for handling differential signals.TIA/EIA-422-B and TIA/EIA-423-B Compliance: Meets or exceeds the requirements of these standards for reliable data transmission.Low Power Consumption: Typically consumes 10 mA, thanks to its BiCMOS (Bipolar and CMOS) process, which combines the strengths of both technologies.Wide Common-Mode Range: Operates with a common-mode input voltage range of ±7V.Input Hysteresis: Features 60 mV of input hysteresis to improve noise immunity.Fail-Safe Circuitry: If inputs are open, the outputs are specified to go high.3-State Outputs: Outputs can be set to a high-impedance state, allowing direct connection to bus-organized systems.Temperature Range: The AM26C32I variant is characterized for operation from -40°C to 85°C. Other temperature grades exist for the AM26C32 series.Data Rate: Supports data rates up to 10 Mbps.
Applications: Primarily used for RS-485, RS-422, and TTL/CMOS logic level communication.
Electrical Characteristics:
Supply Voltage (Vcc):
Operating voltage range: 4.5V to 5.5V (typically 5V).
Input Voltage Range:
Logic Low: 0V to 0.8V (standard logic low level for inputs).
Logic High: 2V to Vcc (typical logic high level).
Output Voltage Swing: The output voltage swing is typically ±2V for differential signals, ensuring proper transmission of data over long distances.
Output Current:
Output Drive Current: Typically ±60mA (for each driver).
Driver Resistance: Low output impedance when driving the differential lines.
Communication Characteristics:
Driver Type: Differential drivers, meaning each pair of outputs produces opposite signals (inverted signals) to allow for high noise immunity and long-distance communication.
Data Rate: Capable of supporting high-speed data rates up to 25 Mbps under optimal conditions.
Number of Drivers: 4 independent differential drivers (i.e., 4 separate channels for data transmission).
Differential Output Voltage: The differential voltage output is typically 2V to 6V (minimum differential voltage of 2V).
Output Type:
Differential: The AM26C32IDR outputs differential signals that are designed for use in RS-422 or RS-485 communication systems.
Output Impedance: Low output impedance for driving the differential bus.
Power Consumption:
Quiescent Current: Typically 1mA per driver (depends on the number of active drivers).
Power Dissipation: Power dissipation is low due to CMOS technology. Under normal operation at 5V, the IC will typically dissipate around 100mW when driving at full load.
Thermal Characteristics:
Operating Temperature Range:
Typically -40°C to +85°C (Industrial temperature range).
Junction Temperature: Maximum junction temperature is 150°C.
