DS36954VX

Overview

The DS36954VX is a low-power quad EIA-485 differential bus transceiver designed for high-speed, parallel, multipoint I/O bus applications. It integrates four drivers and receivers within a compact 20-pin PLCC package. The device operates at a supply voltage of 5 V (4.75 V to 5.25 V) with an operating temperature range of 0°C to +70°C. It supports data rates up to 10 Mb/s and provides greater than 60 mA source/sink currents. Key electrical parameters include a differential driver output voltage of 1.5 V to 2.25 V, propagation delays ranging from 9 ns to 19 ns, and short-circuit output currents reaching ±250 mA.
