ST26LS31 32MHz 3.3V/5V Low-Power Quad Differential Line Driver
Specifications
Product details
Overview
The ST26LS31 is a low-power quad differential line driver operating from a single 3.3V or 5V supply, compliant with ANSI TIA/EIA-422-B and ITU V.11. It delivers data rates up to 32MHz with ±30mA output drive and ±15kV bus ESD (HBM) protection. TTL-compatible inputs and complementary differential outputs drive balanced twisted-pair or parallel transmission lines, and the outputs enter a high-impedance state in power-down mode. Active-high G and active-low GN enable inputs control all four drivers simultaneously for precise device control. Offered in SOP-16 and TSSOP-16 packages over a -40~+125℃ operating temperature range, the ST26LS31 provides a reliable RS-422 interface solution for unidirectional data communication in motor encoders, sensor data transmission and industrial bus control applications.
