description
The SN55451B through SN55454B and SN75451B through SN75454B are dual peripheral drivers designed
for use in systems that employ TTL logic. This family is functionally interchangeable with and replaces the
SN75450 family and the SN75450A family devices manufactured previously. The speed of the devices is equal
to that of the SN75450 family, and the parts are designed to ensure freedom from latch-up. Diode-clamped
inputs simplify circuit design. Typical applications include high-speed logic buffers, power drivers, relay drivers,
lamp drivers, MOS drivers, line drivers, and memory drivers.
The SN55451B/SN75451B, SN55452B/SN75452B, SN55453B/SN75453B, and SN55454B/SN75454B are
dual peripheral AND, NAND, OR, and NOR drivers, respectively (assuming positive logic), with the output of
the logic gates internally connected to the bases of the npn output transistors.
The SN55’ drivers are characterized for operation over the full military range of – 55°C to 125°C. The SN75’
drivers are characterized for operation from 0°C to 70°C.
PRODUCTION DATA information is current as of publication date.
Products conform to specifications per the terms of Texas Instruments
standard warranty. Production processing does not necessarily include
testing of all parameters.

Voltage values are with respect to network GND, unless otherwise specified.
This is the voltage between two emitters of a multiple-emitter transistor.
This value applies when the base-emitter resistance (RBE) is equal to or less than 500
Ω.
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.
