ULN2803LW Darlington

 

Description

The ULN2803LW is High-voltage, High-current Darlington Arrays.

Featuring continuous load current ratings to 500 mA for each of the drivers, the Series ULN28xxA/LW and ULQ28xxA/LW highvoltage, high-current Darlington arrays are ideally suited for interfacing between low-level logic circuitry and multiple peripheral power loads.

Typical power loads totaling over 260 W (350 mA x 8, 95 V) can be controlled at an appropriate duty cycle depending on ambient temperature and number of drivers turned on simultaneously. Typical loads include relays, solenoids, stepping motors, magnetic print hammers, multiplexed LED and incandescent displays, and heaters. All devices feature open-collector outputs with integral clamp diodes.

The ULx2803A, ULN2803LW, ULx2823A, and ULN2823LW have series input resistors selected for operation directly with 5 V TTL or CMOS. These devices will handle numerous interface needs —
particularly those beyond the capabilities of standard logic buffers.

SMF05 Datasheet PDF – 5V, TVS Diode Array – Semtech

Part Number: SMF05

Marking : F05

Function: TVS diode array For ESD and Latch-Up Protection

Manufacturer: Semtech Corporation

Image and Pinouts:

SMF05 datasheet

 

Description

The SMF series TVS arrays are designed to protect sensitive electronics from damage or latch-up due to ESD and other voltage-induced transient events. They are designed for use in applications where board space is at a premium. Each device will protect up to four lines.

They are unidirectional devices and may be used on lines where the signal polarities are above ground. TVS diodes are solid-state devices designed specifically for transient suppression. They feature large cross-sectional area junctions for conducting high transient currents.

They offer desirable characteristics for board level protection including fast response time, low operating and clamping voltage, and no device degradation.

Applications:

1. Cellular Handsets and Accessories
2. Cordless Phones
3. Personal Digital Assistants (PDA’s)
4. Notebooks & Handhelds
5. Portable Instrumentation
6. Digital Cameras
7. Peripherals
8. MP3 Players
