PRL-444RS, 4 Channel TTL/CMOS to RS422 Level Translator and Line Driver

Applications: TTL to RS422 Logic Level Translation Conversion of Single-Ended TTL Signals to Differential Signals for Driving Long Lines Mini Modular Instrument for interfacing with High Speed Data Communications Equipment Features: 40 MHz Typical Maximum Clock Rate 4 Single Ended Inputs with Selectable 50 Ω or 1 kΩ Termination 4 RS422 Outputs for Driving 50 Ohm Cables into 124 Ω Floating Loads SMA or RJ45 I/O Connectors Single Supply, +7.5 VDC to +12 VDC, operation Ready-to-Use 1.3 x 2.9 x 2.9-in. or 1.3 x 2.9 x 3.9-in Module includes a ±8.5 V/1.8 A AC/DC Adapter Description: The PRL-444RS is a 4 Channel TTL to RS422 translator module, available with either SMA or RJ45 I/O connectors. The input resistance of the PRL-444RS inputs can be selected to be either 50 Ω or 1 kΩ by a common toggle switch. The 1 kΩ inputs are desirable when interfacing with low power circuits. The four pairs of complementary outputs are designed for driving floating 124 Ω loads, normally the con
