DS75451/2/3
Series Dual Peripheral Drivers
General Description
Features
n 300 mA output current capability
n High voltage outputs
The DS7545X series of dual peripheral drivers is a family of
versatile devices designed for use in systems that use TTL
logic. Typical applications include high speed logic buffers,
power drivers, relay drivers, lamp drivers, MOS drivers, bus
drivers and memory drivers.
n No output latch-up at 20V
n High speed switching
n Choice of logic function
The DS75451, DS75452 and DS75453 are dual peripheral
AND, NAND and NOR drivers, respectively, (positive logic)
with the output of the logic gates internally connected to the
bases of the NPN output transistors.
n TTL compatible diode-clamped inputs
n Standard supply voltages
n Replaces TI “A” and “B” series

Switching Characteristics (Continued)
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: Voltage values are with respect to network ground terminal unless otherwise specified.
Note 3: The voltage between two emitters of a multiple-emitter transistor.
Note 4: The maximum voltage which should be applied to any output when it is in the “OFF” state.
Note 5: Both halves of these dual circuits may conduct rated current simultaneously; however, power dissipation averaged over a short time interval must fall within
the continuous dissipation rating.
Note 6: Unless otherwise specified min/max limits apply across 0˚C to +70˚C range. All typicals are given for V
= +5V and T = 25˚C.

Note 7: 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.
