DS26C31TM/NOPB

The Texas Instruments DS26C31TM/NOPB is a CMOS Quad TRI-STATE Differential Line Driver. It is designed for digital data transmission over balanced lines and meets EIA standard RS-422 requirements. This device features 4 transmitters and 0 receivers, operating in a half-duplex mode. It supports a maximum signaling rate of 30 Mbps and has a common-mode range of -14 to 14 V, with fault protection from -0.5 to 7 V. The driver operates from a single 5-V supply (4.5V to 5.5V) and consumes a low quiescent current of up to 2000 µA.

This line driver is suitable for constructing serial and terminal interfaces while maintaining minimal power consumption. It accepts TTL or CMOS input levels and translates them to RS-422 output levels. The outputs are tri-state, allowing connection to system buses, and will not load the line when VCC is 0 V. The DS26C31TM/NOPB is available in a 16-SOIC surface mount package and operates within a temperature range of -40°C to 85°C. Typical propagation delays are 6 ns with an output skew of 0.5 ns.
