DS75365 Quad TTL-to-MOS Driver
General Description
The DS75365 is a quad monolithic integrated TTL-to-MOS driver and interface circuit that accepts standard TTL input signals and provides high-current and high-voltage output levels suitable for driving MOS circuits. It is used to drive address, control, and timing inputs for several types of MOS RAMs including the 1103.
The DS75365 operates from the TTL 5V supply and the MOS VSS and VBB supplies in many applications. This device has been optimized for operation with VCC2 supply voltage from 16V to 20V, and with nominal VCC3 supply voltage from 3V to 4V higher than VCC2. However, it is designed so
as to be usable over a much wider range of VCC2 and VCC3. In some applications the VCC3 power supply can be elimi-
nated by connecting the VCC3 to the VCC2 pin.

YOperates from standard bipolar and MOS supply voltages
YTwo common enable inputs per gate-pair
YHigh-speed switching
YTransient overdrive minimizes power dissipation
YLow standby power dissipation
Features
YQuad positive-logic NAND TTL-to-MOS driver
YVersatile interface circuit for use between TTL and high-current, high-voltage systems

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 at these limits. The table of ``Electrical Characteristics'' provides conditions for actual device operation.
Note 2: Unless otherwise specified, min/max limits apply across the 0§C to a70§C range for the DS75365. All typical values are for TA e 25§C and VCC1 e 5V and VCC2 e 20V and VCC3 e 24V.
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.
Note 4: This rating applies between any two inputs of any one of the gates.
