ST26C31B CMOS quad 3-state differential line driver Features TTL input compatible Typical propagation delay: 6 ns Typical output skew: 0.5 ns Output will not load line when V = 0 V CC Meets the requirements of EIA standard DIP-16 SO-16 RS-422 Operation from single 5 V supply 3-state outputs for connection to system buses Low quiescent current Available in surface mount TSSOP16 Description The ST26C31B is a quad differential line driver designed for digital data transmission over balanced lines and meets all the requirements of EIA standard RS-422 while retaining the low power characteristics of CMOS. The ST26C31B accepts TTL or CMOS input levels and translates these to RS-422 output levels. This part uses special outputs circuitry common to all four drivers. All outputs are protected against damage due to electrostatic discharge by diode to V and ground. CC Table 1.
