SN5545xB, SN7545xB Dual-Peripheral Drivers for High-Current, High-Speed Switching
1 Features
3 Description
•
•
•
The SN5545xB and SN7545xB devices are dualperipheral 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. Diodeclamped inputs simplify circuit design.

The SNx5451B, SNx5452B, SNx5453B, and
SNx5454B devices 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 SN5545xB drivers are characterized for
operation over the full military range of –55°C to
125°C. The SN7545xB drivers are characterized for
operation from 0°C to 70°C.

Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings
only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended
Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
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.

9 Detailed Description
9.1 Overview
The SN7545xB and SN5545xB devices provide dual-output drivers with AND, NAND, NOR, or OR logic inputs. If
each logic input is set to the appropriate voltage level, then the output driver will turn on, pulling the driver to
ground and allowing current to flow.

10 Application and Implementation
NOTE
Information in the following applications sections is not part of the TI component
specification, and TI does not warrant its accuracy or completeness. TI’s customers are
responsible for determining suitability of components for their purposes. Customers should
validate and test their design implementation to confirm system functionality.
10.1 Application Information
Typically the SN75451B device drives a high-voltage or high-current peripheral from an MCU or logic device that
cannot tolerate these conditions. The following design is a common application of the SN75451B device, driving
an LED using one channel and a high voltage peripheral using the other. In this configuration, the LED will turn
on whenever the high voltage peripheral is on.

10.2.1 Design Requirements
Each of the inputs to the logic gate should never float. If one of the inputs is floating, then the logic gate could be
in an unknown state. Be sure to connect ground or VCC to any unused input channels.
10.2.2 Detailed Design Procedure
1. Recommended Input Conditions:
– For specified high and low levels, see VIH and VIL in Recommended Operating Conditions.
– The input voltage must not exceed the VI specified in Absolute Maximum Ratings.
2. Recommended Output Conditions:
– It is recommended that the load current not exceed 300 mA.
– The load current must never exceed the IOK noted in Absolute Maximum Ratings.

11 Power Supply Recommendations
The power supply can be any voltage between the minimum and maximum supply voltage rating located in
Recommended Operating Conditions. The VCC pin should have a bypass capacitor to prevent power disturbance.
A 0.1-µF capacitor is suitable for this device.
12 Layout
12.1 Layout Guidelines
Thin traces can be used on the input due to the low-current logic that is used to drive the SNx545xB devices.
Take care to separate the input channels to eliminate crosstalk. These traces are recommended for the output to
be able to drive high currents. Be sure to connect ground or VCC to any unused input channels, and use a
bypass capacitor on the VCC pin to prevent any power glitches.
