Quad Line Driver with NAND
Enabled Three-State Outputs
AM26LS31
The Motorola AM26LS31 is a quad differential line driver intended for
digital data transmission over balanced lines. It meets all the requirements of
EIA–422 Standard and Federal Standard 1020.
The AM26LS31 provides an enable/disable function common to all four
drivers as opposed to the split enables on the MC3487 EIA–422 driver.
The high impedance output state is assured during power down.
• Full EIA–422 Standard Compliance
• Single + 5.0 V Supply
t • Meets Full VO = 6.0 V, VCC = 0 V, IO 100 µA Requirement
• Output Short Circuit Protection
• Complementary Outputs for Balanced Line Operation
• High Output Drive Capability
• Advanced LS Processing
• PNP Inputs for MOS Compatibility
