DS1692/DS3692 TRI-STATE (R) Differential Line Drivers General Description The DS1692/DS3692 are low power Schottky TTL line drivers electrically similar to the DS1691A/DS3691 but tested to meet the requirements of MIL-STD-188-114A (see Application Note AN-216). MIL-STD-188-114A type 1 driver specifications can be met by adding an external three resistor voltage divider to the output of the DS3692/1692. The DS3692/ 1692 feature 4 buffered outputs with high source and sink current capability with internal short circuit protection. With the mode select pin low, the DS1692/DS3692 are dual differential line drivers with TRI-STATE outputs. They feature 10V output common-mode range in TRI-STATE and 0V output unbalance when operated with 5V supply. Multipoint applications in differential mode with waveshaping capacitors is not allowed. Features n Short circuit protection for both source and sink outputs n 100 transmission line drive capability n Low ICC and IEE power consumption: Differential mode: ICC = 9 mA/driver typ, IEE = 5 mA/driver typ n Low current PNP inputs compatible with TTL, MOS and CMOS n Adaptable as MIL-STD-188-114A type 1 driver Logic Diagram (12 Circuit Shown) DS005784-1 Connection Diagram Inputs Outputs Mode A (D) Disable1 (2) A (D) B (C) 0 0 0 0 1 0 0 1 0 1 0 0 1 1 TRI-STATE TRI-STATE 1 0 TRI-STATE TRI-STATE DS005784-2 *Contact Product Marketing for availability.
