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 inter-
faces while maintaining minimal power consumption.
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.
All inputs are protected against damage due to electrostatic
discharge by diodes to V
