| ST26C31 CMOS quad tri-state differential line driver General features s s s s s TTL input compatible Typical propagation delay: 6ns Typical output skew: 0.5ns Output will not load line when VCC = 0V Meets the requirements of EIA standard RS-422 Operation from single 5V supply 3-state outputs for connection to system buses Low quiescent current Available in surface mount TSSOP16 DIP-16 SO-16 s s s s Description The ST26C31 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 ST26C31 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.

All typical are given for VCC=5V and Ta = 25C Skewis defined as the difference in propagation delays between complementary outputs at the 50% point. Output disable time is the delay from the control input being switched to the output transistors tuning off. The actual disable times are less than indicated due to the delay added by RC time constant of the load. CPD determines the no load dynamic power consumption, PD = CPDVCC2, f = ICCVCC, and the no load dynamic current consumption, PD = CPD VCCf + ICC . 4 7/15 Package mechanical data ST26C31 4 Package mechanical data In order to meet environmental requirements, ST offers these devices in ECOPACK(R) packages.
