DS26C31T中文资料CMOS 四路三态差动线路驱动器数据手册TI规格书

描述 Description

The DS26C31 device is a quad differential line driver designed for digital data transmission over balanced lines. The DS26C31T meets all the requirements of EIA standard RS-422 while retaining the low power characteristics of CMOS. The DS26C31M is compatible with EIA standard RS-422; however, one exception in test methodology is taken(2). This enables the construction of serial and terminal interfaces while maintaining minimal power consumption.
The DS26C31 accepts TTL or CMOS input levels and translates these to RS-422 output levels. This part uses special output circuitry that enables the drivers to power down without loading down the bus. This device has enable and disable circuitry common to all four drivers. The DS26C31 is pin compatible to the AM26LS31 and the DS26LS31.
All inputs are protected against damage due to electrostatic discharge by diodes to VCC and ground.
