QUAD DIFFERENTIAL LINE DRIVER SEPARATE LOGIC BIAS AND DRIVER BIAS, WITH TRI-STATE OUTPUTS ET7272B FEATURES Supply (Bias) Voltage Range 3.5V to 30V Operation to 800KHz CMOS and TTL Compatible Inputs logic bias and driver supply pins Separate www.DataSheet4U.com Optional single supply operation for moderate power applications High Impedance Buffered Inputs with hysteresis Tri-State outputs 80mA peak SINK/SOURCE current This part is available in 16L SOIC or 20L TSSOP (all Pb-free) packages, or as die. PACKAGE Die Only 16 Lead SOIC 20 Lead TSSOP SUFFIX -C -SOP -TSS (Pb-free) -----------SOP-LF -TSS-LF APPLICATIONS: Encoders Industrial controls DESCRIPTION These line drivers are pin compatible with 26LS31 in applications where pin 4 = 5V and pin 12 = GND. Internal clamp diodes allow trouble-free operation when driving cable lengths exceeding 100m. Split supplies are provided to minimize standby power dissipation in high voltage applications. The logic should be powered from a regulated 5V supply at the VccBias pin. The output stages may then be powered by a separate supply at VccDrivers, up to 30V. Output voltage swings of 0.3V to VCC-1.9V are typical. The outputs are protected against shorts to ground, shorts to Vcc and to other outputs, by a two-fold scheme of current limiting and thermal shutdown. This assures highly reliable operation in harsh environments. The outputs may be placed into a high impedance state by application of a logic high at the ...
