L6452 is a chip designed by ST to drive two 13x16 matrix ink jet print heads in printer applications. The output stage is able to source simultaneously 400 mA on each of the 16 power lines (columns) with a duty cycle of 33% in normal printing and 66% in head pre-heating. On the address lines (rows), the load is only capacitive (MOS FET driving capability). The driver can control two print heads, but only one is active at a time. The address scanning counter is included and can be disabled to allow a different scanning scheme. In order to avoid output activation during the supply transient, an internal power-up system is implemented. As supporting function, L6452 is capable of sensing the head silicon temperature and to electrically check each nozzle. The device is also integrating a thermal protection.

ST232B and ST232C are 5V powered multi-channel RS-232 drivers and receivers. The features include a supply voltage range of 4.5V to 5.5V, a supply current of 5mA with no load, a transmitter output voltage swing of ±7.8V, controlled output slew rate, a receiver input voltage range of ±30V, a data rate of 220kbps, and an operating temperature range of -40°C to 85°C or 0°C to 70°C.

The ST75185C is a single-chip solution with multiple RS-232 drivers and receivers. It meets and exceeds the requirements of EIA/TIA-232-E and ITU V.28 standards, and is designed to support data rates up to 120 kbps.

ULN2001, ULN2002, ULN2003, and ULN2004 are 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. These versatile devices are useful for driving a wide range of loads, including solenoids, relays, DC motors, LED displays, filament lamps, thermal printheads, and high power buffers.

The TD310 is a driver designed to drive one, two or three power IGBT/MOS and pulse transformer. It includes a current sense comparator which can disable the output drivers in case of overcurrent and signal the event to a controller through an alarm output. Additionally, the TD310 includes an uncommitted op-amp which can be used for current measurement or other general purposes. Programmable undervoltage lockout and standby mode make the TD310 suitable for various environments and applications.

The L6370 is an industrial intelligent power switch with features including 2.5A output current, 9.5V to 35V supply voltage range, internal current limiting, thermal shutdown, open ground protection, etc.

The L6376 is a monolithic quad intelligent power switch with four independent outputs and a current limit of 0.5A. It is built using multipower BCD technology and is designed for driving inductive, capacitive, or resistive loads. The device features extensive electrical protections and is suitable for general purpose industrial applications.

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. The versions interface to all common logic families. These versatile devices are useful for driving a wide range of loads including solenoids, relays, DC motors, LED displays, filament lamps, thermal print heads and high power buffers.

This document describes the features and characteristics of the ULN2065B, ULN2067B, ULN2069B, and ULN2075B quad Darlington switches, revised in January 2009. These switches are designed to interface logic to high current, high voltage loads. Each Darlington switch can deliver up to 1.5 A, with a minimum breakdown voltage of 80 V and a sustaining voltage of at least 35 V. The ULN2067B and ULN2069B models have integral suppression diodes for inductive loads and common emitters. The ULN2075B features an isolated Darlington pinout and is suitable for emitter follower configurations. The inputs of ULN2065B, ULN2069B, and ULN2075B are compatible with popular 5 V logic families, while the ULN2067B is compatible with 6-15 V CMOS and PMOS. The ULN2069B model includes a pre-driver stage to reduce loading on the control logic.
