www.DataSheet4U.com 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 VCC = 0 V Meets the requirements of EIA standard RS-422 Operation from single 5 V supply 3-state outputs for connection to system buses Low quiescent current Available in surface mount TSSOP16 DIP-16 SO-16 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 VCC and ground. Table 1.
