DS26C31T/DS26C31M
CMOS Quad TRI-STATE
General Description
The DS26C31 is a quad differential line driver designed for
digital
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 (Note 8). This enables the construction of serial and
terminal interfaces while maintaining minimal power con-
sumption.
The DS26C31 accepts TTL or CMOS input levels and trans-
lates these to RS-422 output levels. This part uses special
output circuitry that enables the drivers to power down with-
out loading down the bus. This device has enable and dis-
able circuitry common to all four drivers. The DS26C31 is pin
compatible to the AM26LS31 and the DS26LS31.
