DS0026
Dual High-Speed MOS Driver
General Description
DS0026 is a low cost monolithic high speed two phase MOS
clock driver and interface circuit. Unique circuit design provides both very high speed operation and the ability to drive
large capacitive loads. The device accepts standard TTL
outputs and converts them to MOS logic levels. The device
may be driven from standard 54/74 series and 54S/74S
series gates and flip-flops or from drivers such as the
DS8830 or DM7440. The DS0026 is intended for applications in which the output pulse width is logically controlled;
i.e., the output pulse width is equal to the input pulse width.
The DS0026 is designed to fulfill a wide variety of MOS
interface requirements. Information on the correct usage of
the DS0026 in these as well as other systems is included in
the application note AN-76.

Note 1: “Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaranteed. Except for “Operating Temperature Range”
they are not meant to imply that the devices should be operated atthese limits. The table of “Electrical Characteristics provides conditions for actual device operation.
Note 2: These specifications apply for V
+−V−
= 10V to 20V, CL= 1000 pF, over the temperature range of 0˚C to +70˚C for the DS0026CN.
Note 3: All currents into device pins shown as positive, out of device pins as negative, all voltages referenced to ground unless otherwise noted. All values shown
as max or min on absolute value basis.

Switching Characteristics (Continued)
Note 4: All typical values for TA= 25˚C.
Note 5: Rise and fall time are given for MOS logic levels; i.e., rise time is transition from logic “0” to logic “1” which is voltage fall.
Note 6: The high current transient (as high as 1.5A) through the resistance of the internal interconnecting V
−
lead during the output transition from the high state
to the low state can appear as negative feedback to the input. If the external interconnecting lead from the driving circuit to V
−
is electrically long, or has significant
dc resistance, it can subtract from the switching response.
