Overview
The ULQ2001A, produced by STMicroelectronics, is a high voltage, high current Darlington array. This device contains seven open collector Darlington pairs with common emitters, making it highly versatile for various applications. Each channel is rated at 500 mA and can withstand peak currents of 600 mA. The ULQ2001A is designed to interface with all common logic families, including TTL, CMOS, PMOS, and DTL. It is available in 16-pin plastic DIP packages and small outline packages (SO16), with the latter option also available as an Automotive Grade product.
