SLRS021D – DECEMBER 1967 – REVISED JANUARY 2017 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. 1 Characterized for Use to 300 mA
High-Voltage Outputs up to 30 V
No Output Latch-Up at 20 V (After Conducting
