Product Overview
The AM26LS31CDR is a Texas Instruments Signal_Chain device described as a quadruple differential line driver. It provides four complementary-output drivers and is intended for interfaces that meet or exceed ANSI TIA/EIA-422-B and ITU Recommendation V.11 requirements. The device operates from a 5 V nominal single supply, with recommended AM26LS31C supply limits of 4.75 V minimum and 5.25 V maximum.
This part is supplied in an SOIC (16), 9.9 mm × 3.91 mm package. Assembly-related limits from the datasheet include a 260 °C maximum lead temperature measured 1.6 mm from the case for 10 seconds. Absolute maximum ratings include 7 V maximum supply voltage, 7 V maximum input voltage, 5.5 V maximum output off-state voltage, and -65 °C to 150 °C storage temperature.
Electrical and timing data support use in differential digital signaling applications. The device specifies 2.5 V minimum high-level output voltage at IOH = -20 mA, 0.5 V maximum low-level output voltage at IOL = 20 mA, 14 ns typical low-to-high and high-to-low propagation delays, and 1 ns typical output-to-output skew under the listed test conditions.
