General Description
Through simple logic control, the DS7831/DS8831,
DS7832/DS8832canbe usedas eithera quad single-end-line driverora dual differentialline driver. Theyare spe-
cifically designedfor party line (bus-organized) systems.
The DS7832/DS8832 doesnot havethe VCC clamp diodes
foundonthe DS7831/DS8831.
The DS7831 and DS7832are specifiedfor operation over
the b55§Cto a125§C military temperature range. The
DS8831 and DS8832are specifiedfor operation overthe
0§Cto a70§C temperature range.
Features Series 54/74 compatible17ns propagation delay Verylow output impedanceÐhigh drive capability40mA sinkand source currents Gating controlto allow either single-endedor differen-
tial operation High impedance output state which allows many out-
putstobe connectedtoa commonbusline
