TRS3221ECPW
Features of TRS3221ECPW
? RS-232 Pin ESD Protection
- Human-Body Model at 15 kV (HBM)
? ?8 kV (IEC 61000-4-2, contact discharge) (IEC 61000-4-2, contact discharge)
? ?15 kV (IEC 61000-4-2, air-gap discharge) (IEC 61000-4-2, air-gap discharge)
? Complies with or outperforms TIA/EIA-232-F and ITU v.28 requirements
? Runs off of a 3-V to 5.5-V VCC supply
? Can run at up to 250 kbit/s
? There is one receiver and one driver
? 16-pin VQFN package, nearly chip-scale (RGT, 82% smaller than TSSOP package)
? Typical low standby current: 1 A
? Four 0.1-F external capacitors
? Accepts 3.3-V supply and 5-V logic input.
? A different, 1 Mbit/s, high-speed pin-compatible device
? For power conservation, the auto-power down feature immediately disables drivers.

UC3843 Current Mode PWM Controller IC DIP-8 Package
ULN2003 7 Darlington Transistor Arrays IC DIP-16 Package
The ULN2003 is high-voltage, high-current Darlington arrays each containing seven open collector Darlington pairs with common emitters. Each channel is rated at 500 mA and can withstand peak currents of 600 mA. Suppression diodes are included for inductive load driving and the inputs are pinned opposite the outputs to simplify board layout.
